Routes

Old Oregon 23
An example of an original Oregon Route maker.

A Route is often referred to by the Oregon Department of Transportation (ODOT) as a "Signed Route" or a "Map Route". Until recently, these Route Numbers did not coincide with the Highway Numbers ODOT used to manage its inventory of State Maintained Highways. Routes were a separately managed number system used for navigation between points. For example, Routes can be assigned to County Roads and City Streets as required, especially in jurisdiction where State Highways were ceded to local governments agencies.

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

Until 2002, 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 notes on the associated web pages of "Recommended Route" that I think would improve the Route number system.

Interstate Routes

Interstate Routes were established with the passage of the National Interstate and Defense Highways Act on June 29th, 1956. All Interstate Route assignments are managed by the American Association of State Highway and Transpiration Officials (AASHTO) and must also meet guidelines established by the Federal Highway Administration. Due to these guidelines, Interstate Routes are assigned only to State Maintained Highways.

Mainline Interstate Route Numbers are one or two digit numbers with the following characteristics:

  • East-West routes are even numbers with the lowest numbers in the South and the highest numbers in the North (I-82 and I-84).
  • North-South routes are odd numbers with the lowest numbers in the West and the highest numbers in the East (I-5).
  • Cardinal Direction Suffixes of "N", "S", "E", "W" were added to the one and two digit routes that were extended spurs or splits in the route (I-80N).
  • Route numbers ending in "0" or "5" are considered transcontinental.

Spur and Loop Interstate Route Numbers are three digit numbers with the following characteristics:

  • Spur Routes into cities are three digit numbers where the first digit was an odd number and the next two digits reflected the Mainline Route they were associated with (I-105, I-305 and I-505).
  • Loop Routes around cities or into urban areas are three digit numbers where the first digit was an even number and the next two digits reflected the Mainline Route they were associated with (I-205 and I-405).

Business Interstate Routes were designed to help travelers find businesses in City Centers off of Mainline Interstates. Oregon does not use Business Interstate Routes, but uses concurrent United States and Oregon Routes as Business Routes.

In the 1960's, AASHTO decided to work toward the elimination of lettered suffixed route numbers, which led to the renumbering of I-80N to I-84 on May 1st, 1980.

United States Routes

United States (US) Routes were established on November 11th, 1926, by the American Association of State Highway Officials (AASHO), the predecessors of today's American Association of State Highway and Transpiration Officials (AASHTO). US Route assignments are still managed by AASHTO. US Routes are not assigned exclusively to State Maintained Highways, but also traverse local County Market Roads and City Streets.

Mainline United States Route Numbers are one or two digit numbers (with US-101 being an exception) with the following characteristics:

  • East-West routes are even numbers with the lowest numbers in the North and the highest numbers in the South (US-20, US-26, US-28 and US-30).
  • North-South routes are odd numbers with the lowest numbers in the East and the highest numbers in the West (US-95, US-97, US-99 and US-101).
  • Cardinal Direction Suffixes of "N", "S", "E" or "W" were added to the one and two digit routes that were extended spurs or splits in the route (US-30N, US-30S, US-99E and US-99W).
  • Route numbers ending in "0", "1" or "5" are considered transcontinental.

Three digit United States Routes were intended to be collectors and spurs of Mainline United State Routes. However, many three digit routes have taken on Mainline characteristics. Typically, three digit route numbers are "children" of the "parent" mainline route, with the last two digits identifying the one or two digit Mainline United States Route (US-126, US-197, US-199, US-395, US-630 and US-730). However, there are some notable exception in other parts of the US.

In addition, United States Routes can have Auxiliary designations for special routes. Oregon uses the following designations:

  • Alternate (Currently not in use)
  • Business
  • By-Pass
  • Spur

AASHTO current policy encourages the consolidation and elimination of short United States Routes, as well as the elimination of United States Routes that are concurrent with Interstate Routes. Based on those policies, US-20 and US-26 were extended into Oregon, and US-28, US-99, US-99W, US-99E and US-126 were eventually eliminated. However, base on those policies, US-30 and US-197 would be candidates for elimination as well. US-199, although short, is still used as an Interstate Connector between US-101 in California and I-5 in Oregon.

Oregon State Routes

The Oregon State Highway Commission implement a Primary State Route System in 1932 (also known as a "Signed Route" or "Map Route"), then added a Secondary State Route System in 1936. 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. Again, this was because the primary purpose was for navigation, not as an inventory of State Maintained Highways.

Primary Oregon Route Numbers are one or two digit numbers with the following characteristics:

  • East-West routes are even numbers with the lowest numbers in the Northwest and the highest numbers in the Southeast.
    • ORE-2 through ORE-46 were West of the Pacific Highway #1.
    • ORE-50 through ORE-78 were East of the Pacific Highway #1, but South and West of the Oregon Trail Highway #6.
    • ORE-82 through ORE-90 were North and East of the Oregon Trail Highway #6.
  • North-South routes are odd numbers with the lowest numbers in the East and the highest numbers in the West.
  • Cardinal Direction Suffixes of "N", "S", "E" or "W" were added to the one and two digit routes that were extended spurs or splits in the route (ORE-42S, ORE-99E and ORE-99W).

Secondary Oregon Route Numbers were three digit "200" series routes with the following characteristics:

  • East-West routes were even numbers with the lowest numbers in the North and the highest numbers in the South.
  • North-South routes were odd numbers with the lowest numbers in the East and the highest numbers in the West.

In the 1960's, three digit "100" series routes were introduced as extended primary routes across the state (ORE-138 and ORE-140).

In the 1970's, ORE-99, ORE-99E, ORE-99W and ORE-126 were added when the equivalent United States Routes (US-99, US-99W, US-99E and US-126) were eliminated.

In 2002, the Oregon Highway Commission decided to add Oregon Route designation to all "unsigned" State Maintained Highways, using the associated Highway Number as the Oregon Route Number. This created additional "100" and "200" series Oregon Routes as well as creating "300" and "400" series Oregon Routes. The "500" series Oregon Routes were used in the event using an existing Highway Number would cause a duplication of the Oregon Route System. This change made ineffectual the Primary and Secondary Oregon Route systems and the distinction of Even and Odd Route Numbers.

As part of this plan, agreed to by all 48 States, Oregon designate the following State Highways as part of the United States Route 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.

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

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.
