An example of an original Oregon Highway maker.
A Highway is defined as a road that is maintained by the Oregon Department of Transportation (ODOT) and is identified by a name and an inventory number (sometimes referred to as a Road Number). These numbers normally do not coincide with published and marked Route Numbers seen on road maps.

Due to confusion caused by Oregon's Dual Numbering System, some map publishers in the past incorrectly publish the Highway numbers on maps, even though there was no official Route markings by ODOT.

Before the creation of the Oregon Route System in 1932, the Oregon State Highway Commission (OSHC) used a triangular marker to identify State Maintained Highways.

After the creation of the Route System in 1932, ODOT did not post Highway numbers in any form on their road network. The photo shown below of the Fishhawk Falls Highway #103 near Elsie in 2001 was a rare exception.

On the left, a rare guide sign noting a "secret" highway name and number of the Fishhawk Falls Highway #103 at it's junction with the Sunset Highway #47 (US-26) near Elsie. Since then, ODOT has assigned State Route 103 to Fishhawk Falls Highway #103, and it is now marked with an Oregon 103 Route Marker.
Starting in 2002, ODOT began assigning route numbers to all "unnumbered" Highways. Most of the new Route numbers were assigned to match the Highway number, except when the number assignment would result in a duplication of an existing Route number. In those cases, the "500" series Route numbers were used.

There are still some exception where a Route number has not been officially assigned to a Highway or to a Highways segment. Where these instances occur, I have added a "Recommended Route" comment, where I think a Route number should be assigned.

Classification of Highways
Highway System History
List of Highways
Primary Highways
Secondary Highway
Spur Highways

Classification Of Highways
Primary Highways
The Primary Highway System was first adopted in 1917 creating the first 36 State Highways. Currently, there are 67 active Primary State Highways.

Primary Highway are assigned numbers between 1 and 100. Originally created to be main trunk highways across the state, the Primary designation no longer has any real meaning.
Secondary Highways
The Secondary Highway System was adopted in 1931, transferring control of key County Market Roads under State Jurisdiction so highway improvement could be coordinated at the State level.

Secondary Highways were assigned number ranges above 100, grouped by county of origin. For example, Clatsop County had Highways 102 to 109, Columbia County had Highways 110 to 119, etcetera, up to Malheur County which had Highway 450 to 459.
Spur Highways
Highway Spur have always existed as extenstion of both Primary and Secondary Highways. Before 2010, these Highways always had a "Y" designation with a sequence number. For example:

Highway 455 Y1
Highway 455 Y2

In 2010, ODOT began assigning highway numbers to the various Highway Spurs that branched off Mainline Highways. These Highways were assigned the 480 and 490 range of numbers.
Roadway Numbers
In the event a Highway has a separation, such as a Divided Highway, Freeway, or a One Way Couplet, a Roadway Number is used to identify the parallel segments. They usually are suffixed in parenthesis after the Highway Number. For example, for the Pacific Highway #1 Roadways are usually identified as:

001 (1) - Roadway #1
001 (2) - Roadway #2

Typically, Roadway #1 is the Southbound or Eastbound direction, and Roadway #2 is the Northbound or Westbound direction.
Connection and Frontage Highways
Connection and Frontage Highways are used to identify Connection Ramps and Frontage Road that are maintained by ODOT. Typically, these are associate with ramps and overpasses on Interstate Route and Freeway segments, but are also used on other Highways. They were first used around 1990 as ODOT started creating a Highway Inventory Database for all their maintained milage.

These Highways are identified by a five character Highway Number. The first three numbers identify the Oregon Highway the Connection or Frontage Road is associated with, followed by two letter designation. They were originally as singed in an "alphabetic" order from the Zero Mile Point and incriminated up to the Maximum Mile Point. For example, on the Pacific Highway #1, the original order was:

001AA - Siskiyou Frontage Road
001AB - Siskiyou Highway Connection
001AC - Siskiyou Safety Rest Area Connection
001AD - Green Springs Highway Connection #1
001AE - Green Springs Highway Connection #2

...ending with...

001UO - Jantzen Beach Connection #5

As old Connections Ramps and Frontage Roads are replaced or new ones are built, the next letter sequence is assigned.
Connections on Freeway Interchanges
Connecting ramps on Freeway Interchanges are identified differently depending on the jurisdiction of the intersecting Road or Highway.

Connector Sample 1 In a typical Diamond Interchange, the Connection identifiers are assigned in a counter clockwise fashion.
This example is the North Ashland Interchange on the Pacific Highway #1.
  • Connector 001AI - Off Ramp from Highway #1 Northbound

  • Connector 001AJ - The State Maintained section of the intersecting road

  • Connector 001AK - On Ramp to Highway #1 Northbound

  • Connector 001AL - Off Ramp from Highway #1 Southbound

  • Connector 001AM - On Ramp to Highway #1 Southbound

Connector Sample 2 When an Interchange is the intersection of two State Highways, the Connection identifiers are derived from both Highways. Usually the Connection is associated with the Highway it transitions away from.
This example is the Green Springs Interchange on the Pacific Highway #1 intersecting the Greeen Springs Highway #21.
  • Connector 001AD - Off Ramp from Highway #1 Northbound

  • Connector 001AE - Off Ramp from Highway #1 Southbound

  • HIghway #21 - The intersecting highway.

  • Connector 021AA - On Ramp to Highway #1 Southbound

  • Connector 021AB - On Ramp to Highway #1 Northbound

Connector Sample 3 When an Interchange is the Start on End of a State Highways, two of the Connections are Roadways of the terminating Highway.
This example is the Rock Point Interchange on the Pacific Highway #1 at the termination of the Rouge River Highway #60.
  • Connector 001CC - Off Ramp from Highway #1 Southbound

    HIghway #60 - The intersecting highway.

  • Highway #60 - Roadway #1 - On Ramp to Highway #1 Southbound and the intersecting highway

  • HIghway #60 - Roadway #2 - Off Ramp from Highway #1 Northbound

  • Connector 060AE - On Ramp to Highway #1 Northbound

These are typical examples, but there is many different variations depending on the layout of the Interchange and intersecting roads..

Highway System History
1913 - Origins of Oregon Highway System

1914 Highway Reccomendations
A map of the network of highways recommended by Major H. L. Bowley, Oregon State Highway Engineer, delivered to the Oregon Highway Commission on June 3rd, 1914.

The origins of the Oregon Highway System came with the creation of the first Oregon Highway Commission by the Oregon Legislature and signed by Governor Oswald West on August 12th, 1913. By law, the original Commission consisted of the Governor (Oswald West), Secretary of State (Ben W. Olcott), and the State Treasurer (Thomas B. Kay).

Under this Legislation, funding from the state would be distributed to the counties for Highway Construction. By the time the initial Commission was formed, Multnomah County had already started work on one of the first engineering feats of the newly formed Commission, the Columbia River Highway.

As part of the newly enacted legislation, the new State Highway Engineer, Major H. L. Bowley, was assigned the task of developing the initial highway plan for the State of Oregon, to be delivered to the Oregon Highway Commission by June 3rd, 1914.

He made his recommendation on precise due date on June 3rd, 1914. He recommended the construction of a system of eight State Highways:


The Columbia Highway, starting in Seaside, through Astoria and Portland to Pendleton, then to Freewater (now Milton-Freewater) to the Washington State Line south of Walla Walla.

This was the predecessor of the Columbia River Highway #2 and the Oregon-Washington Highway #8.

1914 Columbia Highway
The proposed Columbia Highway from the 1914 Bowley Plan.

A South East branch of the Columbia Highway (to be named later), running to the southeast from Pendleton running through La Grande, Baker (now Baker City), Huntington, then crossing the Snake River crossing the Idaho State Line around Ontario.

This became the Old Oregon Trail Highway #6.

1914 Columbia Highway, Southeast Branch
The proposed Columbia Highway, Southeast Branch from the 1914 Bowley Plan.

The Oregon Beach Highway running from Seaside south along the coast to the California State Line.

This became the Oregon Coast Highway #9.

1914 Oregon Beach Highway
The proposed Oregon Beach Highway from the 1914 Bowley Plan.

The Pacific Highway, running south from Portland through Salem, Albany, Eugene, and Ashland, then across the California State Line.

This is still the Pacific Highway #1, although with the construction of Interstate 5, many of the original segments were transferred to other State Highways or to local jurisdictions.

1914 Pacific Highway
The proposed Pacific Highway from the from the 1914 Bowley Plan.

The Capitol Highway, running along the west bank of the WIllamette River from Portland to McMinnville, Monmouth, and then joining the Pacific Highway at Albany.

This what was originally the Westside Highway #28, which later became the Westside Highway #3 and eventually to the Pacific Highway West #1W.

1914 Capitol Highway
The proposed Capitol Highway from the 1914 Bowley Plan.

The Dalles-California Highway running from The Dalles through Redmond and Klamath Falls to the California State Line.

With only a few differences, the route is pretty much the same route as the current The Dalles-California Highway #4.

1914 The Dalles-California Highway
The proposed The Dalles-California Highway from the 1914 Bowley Plan.

The Central Oregon Highway running from Wasco, through Prineville to Lakeview and then to the California State Line.

This was never constructed as a contiguous highway, but most of this route is the basis for the Sherman Highway #42, the Crooked River Highway #14, and the Fremont Highway #19.

1914 Central Oregon Highway
The proposed Central Oregon Highway from the 1914 Bowley Plan.

The East-West Highway consisting of two segments.:

  • Segment 1 would run from Eugene to Redmond to Prineville meeting the Central Oregon Highway.
  • Segment 2 left the Central Oregon Highway at Millican, traveling through Burns to meet the Columbia Highway Southeast Branch at Ontario.

This eventually became the McKenzie Highway #15, and portions of the Ochoco Highway #41, and the Central Oregon Highway #7.

1917 - The Creation of the Oregon State Highway Commission and of the Primary Highway System

1917 Highway Reccomendations
A map of the network of highways recommended by Herbert Nunn, Oregon State Highway Engineer, adopted by the Oregon State Highway Commission on November 27th, 1917. Click on the map to see a larger PDF version of the map.

Although the 1913 Oregon Highway Commission Act started getting Oregon "...Out of The Mud", it was determined that under the current statutes, progress wasn't being made fast enough on the demand for a statewide network of All Weather Highways. In addition, the existing Highway plan was not comprehensive enough, with few cross mountain routes, and many communities and county seats not served.

So on February 19th, 1917, Governor James Withycombe signed into law the act creating the Oregon State Highway Commission (OSHC). The new Commission came into existence on March 1st, 1917.

With the new Legislation, the Commission would no longer consisted of the Governor, Secretary of State and State Treasurer serving as "part time" Commissioners. Instead, the Governor would appoint and the Legislature would approve a three person commission with rotating terms. All decisions of the commission required unanimous votes. In addition, $6 Million of funding was given to the Highway Commission to begin build Oregon's Highway infrastructure.


From the 1925 Clauson's Touring Atlas.

Also, the Legislation expanded the Highway plan from 8 Highways to 36 Highways. The new plan included many more Interregnal Highways that crossed the Coast Range and Cascade Range, and served more communities and County Seats.

These Highways would later become the Primary Trunk Highways system, most of which is in use today. The Highways were identified by a name and a one or two digit number and would be marked with a Diamond Shaped Marker as seen in the image to the left.


Listed below are the initial 36 Highways in State Highway Engineer Herbert Nunn's proposal adopted on November 27th, 1917. Click on the link for information on the Highway listed here, or click on the Primary Highways link to look at a list of all current and past Primary Highways.

As part of this plan, agreed to by all 48 States, Oregon designate the following State Highways as part of the US Route Number system:


US-28 John Day Highway #5 - From Ontario to Rock Creek Junction.
Ochoco Highway #41 - From Rock Creek Junction to Redmond.
McKenzie Highway #15 - From Redmond to Springfield
Pacific Highway #1 - From Springfield to Junction City co-routed with US-99.
Siuslaw Highway #34 - From Junction City to Florence.

US-30 The Old Oregon Trail Highway #6 - From the Idaho State Line near Ontario to Pendleton.
Columbia River Highway #2 - From Pendleton to Astoria

US-97 Sherman Highway #42 - From the Biggs Junction Ferry at the Washington State Line to Shaniko Junction.
The Dalles-California Highway #4 - From Shaniko Junction to Klamath Falls,
Ashland-Klamath Falls (Green Springs) Highway #21 - From Klamath Falls to Ashland.

US-99 Pacific Highway #1 - From Washington State Line on the Interstate Bridge in Portland to the California State Line south of Ashland.

US-101 Roosevelt (Oregon Coast) Highway #9 - From Ferry in Astoria at the (Washington State Line to California State Line near Brookings.

US-199 Redwood Highway #25 - From Grants Pass to California State Line south of Cave Junction.

US-630 The Old Oregon Trail Highway #6 (Weiser Spur) - From Idaho State Line at Weiser, ID to Weiser Junction.

US-730 Umatilla Cutoff #37 - From Umatilla to Washington State Line near Wallula, WA. The route alignment was approved in 1926, but the highway wasn't completed until 1933.
1931 - Creation of the Secondary Highway System

Between 1919 and 1931, the Oregon Legislature set aside regular funding to support the building and maintenance of a system of Market Roads managed by the 36 Oregon Counties. With dwindling tax revenues and resources from the onset of the Great Depression, the Oregon Legislature decided to divert funding for the Market Roads to a Secondary Highway System managed by the Oregon State Highway Commission.

The Secondary Highways were created from selected County Market Roads in various counties. They were given Highway Names like the Primary Highways, but were assigned a 3 digit number based on the county of Highway origin. These numbers were assigned in groups of 10 starting with 100 to 109 for Clatsop County in the Northwest part of the state to 450 to 459 in Malheur County in the Southeastern part of the state, with a few exceptions.

1932 - Creation of the State Primary Route System

1935 Oregon Official Road Map Scan
Examples of Oregon and US Route Markers from the back of the 1935 Oregon Official Official Road Map.

Before 1926, the only way for the traveling public to navigate along the Oregon Highway System was to either rely on the "Auto Trail" Network of roads, or to use the Oregon Highway Number System. The problem with the "Auto Trail" Network is that it relied on private management of the signs and markings for a route, and did not keep up with the rapidly changing Highway System. The Oregon Highway Number System was designed to fund and maintain roads, not for easy navigation between communities.

In November of 1926, this all changed with the implementation of the US Route System in Oregon. The new US Route Numbers made it easy to navigate from place to place, because a consistent number referenced a contiguous route across multiple Oregon Highways as well as local Market Roads and City Streets.

The success of the US Route System led the Oregon State Highway Commission to implement a State Route System in 1932 (also known as a "Signed Route" or "Map Route"). The primary purpose of these route numbers to assist the traveling public in navigating around the state along the shortest most direct route to any destination. Like the US Route System, the State Route System would not be exclusively on State Highways, but would also traverse local County Market Roads and City Streets, because the primary purpose was for navigation, not as an inventory of State Maintained Highways.


OR-23
1932 Primary Route Marker

The first Routes posted were the Primary Routes. The Route Marker design was based on the Eagle and Shield symbols on both the Oregon State Seal and State Flag.

Primary Routes were assigned one or two digit numbers with odd numbers running North and South and even numbers running East and West, just like US Routes. Also, odd numbers incremented higher from East to West and the even numbers incremented higher from North to South just like US Routes.

Although the odd numbered Routes (initial numbering from 3 to 51, leaving room for expansion) incremented normally from East to West, the even numbered Routes were assigned by Region of the State. So Route numbers 2 to 46 were for Routes starting West of the Pacific Highway #1, Route numbers 50 to 78 were for Routes starting between Pacific Highway #1 and The Old Oregon Trail Highway #6, and Route numbers 82 to 90 were for Routes that started East of The Old Oregon Trail Highway #6.

1936 - Creations of the State Secondary Route System

OR-206
1936 Secondary Route Marker

In 1936, the Route System was expanded to implement a Secondary Route System for use on the Secondary Highway System. These were the "200" series Route Numbers, again with odd numbers North and South and even numbers East and West.

Rather than create a special Route Marker for Secondary Routes, the Highway Commission used the existing Eagle and Shield marker and just numbers the Secondary Routes in the 200's.

Just like Primary Routes, these Route numbers were assigned with the lowest odd numbers (starting at 201) incrementing from East to West and even numbers (starting at 202) incrementing from North to South, but did not use a specific regional pattern like the Primary Routes did.

Below is a list of the initial State Secondary Routes and the Highways they were assigned to.

1956 - Implementing Interstate Routes in Oregon

I-80N and US 30 Route Markers on Hwy 2 near The Dalles
Interstate 80N and US 30 route markers on Columbia River Highway #2 somewhere east of The Dalles, early 1960's.

On June 29th, 1956, the National Interstate and Defense Highways Act was signed into law by President Dwight D. Eisenhower, ushering in the largest Public Works project ever attempted. The Oregon State Highway Commission and the Highway Division started as quickly as possible to get up to speed. Many of the existing urban links of the Interstate System were already in place, but had many miles of rural routes that would have to be upgraded to Interstate Standards.

On October 22nd, 1966, Oregon became the first State in the country to complete a non-toll Interstate from state line to state line with the completion of Interstate 5 near Canyonville.

2002 - Steps toward eliminating the dual Highway/Route Number Systems in Oregon

Over the years, there has been a great deal of confusion generated by the dual Highway and Route systems in Oregon. Recent studies by the Oregon Department of Transportation (ODOT) has documented some of the issues caused by this dual number system:

  • Confusion with ODOT processes such as developing public reports, internal conversations between groups and indoctrinating new staff.
  • Confusion with public, other state agencies and local agencies in understanding ODOT reports that reference the internal ODOT highway number, in utilizing the ODOT web site and in conversations with ODOT staff.
  • Traveling public confusion caused by a single route going over several internal ODOT highways and the mile posts being based on the internal ODOT highway number as opposed to the signed route.
  • Emergency and incident response confusion (e.g. receiving a TOC, Police or 911 call to a specific mile point and having that same mile point duplicated one or more times on any given route)
  • Confusion and additional complexity when routing/permitting oversize loads.
  • Confusion and potential for miscommunication for issues such as approach permits, development review, etc.
  • Noncompliance with the 2003 Federal Manual on Uniform Control Devices (MUTCD) requires that the distance numbering of milepost markers shall be continuous for each route within a State.
 

Starting in 2002, the Oregon Department of Transportation and the Oregon Transportation Commission (OTC) (the modern equivalent to the Oregon State Highway Commission) has been taking some step in eliminating the dual system.

First, the OTC approved assigning Route Numbers to most non-signed Oregon Highways, assigning Route Numbers that matched Highway Numbers unless there was a duplication. In that case, the new Route Number would be a "500" Series Route Number to avoid duplication.

Second, when jurisdictional changes occurred in Roseburg in 2003 involving the North Umpqua Highway #73, the remaining portion of the Oakland-Shady Highway #234, the East Diamond Lake Highway #425, and Washington, Oak, and Harvard Avenues in Roseburg, the new Highway designation was the North Umpqua Highway #138 to match the Route number of ORE-138. However, there are still portions of ORE-138 that are on the Pacific Highway #1 and the Elkton-Sutherlin Highway #231.

Lastly, ODOT is working on a project to re-milepost ORE-140 to a Route based milepost, versus a Highway based milepost. This is to eliminate the duplicate milepost on the route, as ORE-140 transverse 7 different ODOT Highways. There is not a timeline for this project, nor is there any clear information on what would happen to the Highway Inventory Numbers on the length of the Route.

 

ODOT has discussed many times merging the two systems together, having a "great renumbering" like California and many states have done. What has prevented Oregon from doing this has been money. So many internal systems and Historical information is related to the current dual system, not to mention all the mileposts and signage that would have to be changes would make the task insurmountable. So count on the Highway Numbers and Route Numbers to be around for a long time to come.

Route Recommendation Explanation

The original purpose of the Oregon Route System was to aid in navigation across the state. From the beginning in 1933, Oregon Routes were not only assigned to State Highways, but also to City Streets and County Roads, even though not all State Highways were given Route Numbers.

Starting in 2002, the Oregon Highway Commission began assigning Route Numbers to the remaining unnumbered State Highways to prevent future confusion. However, there are still segments of State Highways that currently do not have a Route Number.

In addition, there are still many instances where Route Numbers are assigned to County Roads or City Streets, usually due to jurisdictional transfers.

So based on this history, I have listed Recommended Route Number additions and deletions that I feel would aid in navigation within the state. The criteria is either:

  • The State Highway or State Highway segment currently does not have a Route Number.
  • The elimination of "split" Routes by the use of a SPUR or BUSINESS designation.
  • A continuation of a Route along a County Road or City Street that would provide continuity of the Route System.
  • Elimination of a Route where a jurisdictional transfer has removed a Highway from state maintenance and the State Route Number no longer provides navigational benefit.
