Details

Location

U.S. 20 | ​​U.S. 20 and the intersection of Cook Ave./OB Riley​ in Tumalo

Cost and Funding

​Short-term - $2.2 million ($1.1 million from ODOT, 1.1 million from Deschutes County)
Long-term - $10-30 million (not yet funded) 

Benefits

Current Status
ODOT and Deschutes County have partnered to provide additional funding for project development. We're currently in the public outreach phase, which will lead towards a preferred solution that will be taken to a 30% design. This will allow us to be shelf ready when and if construction funding is identified.

Overview
This project will develop solutions that address short and long-term safety goals and congestion problems while meeting the needs of the many stakeholders that use this section of US 20.

​​U.S. 20 is a critical part of the State’s transportation system. U.S. 20 is an important freight route that supplies goods and services to central and eastern Oregon. It is also an important highway for local commuting traffic and the surrounding community. Keeping highways safe and traffic moving are critical parts the Oregon Department of Transportation’s mission. 

Long-term solutions 
A long-term solution is needed to address safety and operations on US 20 through Tumalo, while maintaining connectivity and mobility of the community. From 2008 - 2012, ODOT worked with stakeholders including the Federal Highway Administration, Deschutes County, emergency service providers, the freight industry and property and business owners in the Tumalo area to develop potential concept alternatives that meet the long-term goals of the project.

ODOT and Deschutes County have now partnered to re-initiate project developement efforts in order to determine the preferred long-term solution and develop it to 30% design. The project developement process will consist of the following phases: 

  • ​Phase 1: Perform traffic analysis and an alternatives analysis to evaluate previously adopted concepts and new potential solutions, including a multi-lane roundabout, to be included in Phase 2. 
  • Phase 2: Refine potential concept alternatives and conduct an extensive public outreach process to gain broad community and stakeholder input on potential solutions. Determine the preferred long-term solution for the project and develop to 30% design. 
  • Phase 3 (not yet funded): Begin the right-of-way acquisition process and develop the project to Final Design. 

Past safety improvements 
ODOT and Deschutes County have implemented several short term solutions to help improve the US 20 Tumalo corridor. These include:
  • Speed studies conducted in 2005, 2007 and 2009. In 2005, the speed through Tumalo was reduced to 50mph, and in 2007, the speed was reduced to 45mph
  • Advance speed zone signs installed east and west of Tumalo to alert drivers of the speed reduction ahead.
  • Realignment of O.B. Riley Road and created a 4-way intersection.
  • Striping modifications to make it safer for northbound traffic on O.B. Riley Road to turn right and prevent eastbound traffic on US 20 from changing lanes in the intersection.
  • Advance intersection signs with street names to improve awareness of upcoming intersections.
  • Enlarged stop signs for Bailey Road and 7th Street to improve driver compliance.
  • Stop bar realignment to improve visibility of vehicles on the side streets.
  • Left hand turn refuge on US 20 at the intersection of Bailey Road and 7th Street.
  • Raised curb median at US 20 and 7th Street/Bailey Road.

What Problem Will This Improve?

Safety
There have been a total of 21 crashes on US 20 between the intersections of 5th Street and Cook Avenue/OB Riley Road over a six year period between 2009 and 2014.  Of these crashes, 14 were intersection related.  Nine of the crashes resulted in injuries, of which two involved severe injuries. There were no fatalities during this period. 43% of the intersection crashes were left turning and 29% crossing  maneuvers, with the major cause being failure to yield right-of-way.

Crash data shows an improvement over data collected from 2005 to 2008 which showed a total of 24 in this corridor of which 19 people were injured. 

Congestion along US 20 in Tumalo 
The population growth in Tumalo and the surrounding area and the increase of traffic on US 20 are increasing congestion and backups on side streets and making it difficult for drivers to turn onto the highway from local streets. In 2019, traffic volumes are expected to increase to 15,200, nearly double counts in 2000.
