Supplying safety and travel-time predictability to a regional economic engine

Preliminary design phase is underway to relieve congestion by widening Interstate 205 and upgrading the Abernethy Bridge and other I-205 bridges in the project limits so they can withstand a major earthquake.

Project Overview

More than 100,000 vehicles use this section of I-205 each day and drivers experience 5 ½ hours of congestion daily. This project will help relieve congestion by adding a third lane in each direction on a seven-mile stretch of I-205 between Stafford Road and OR 99E.

The Abernethy Bridge, which crosses the Willamette River between West Linn and Oregon City, and the eight other I-205 bridge sites along this stretch of highway are vulnerable to severe damage or collapse in the event of a major earthquake. ODOT has designated I-205 as a statewide north-south lifeline route, which means it must be operational quickly if an earthquake renders other roadways unusable or impassable. It will be a critical route in getting supplies and services to the region.

This project will upgrade these bridges so they can withstand a major earthquake.

629 crashes in this corridor 2010-2014, 5.5 hours congestion per day, $5.5M cost of injuries, damage, delay and fuel from crashes


Preliminary Design Phase: July 2017 - June 2018

The purpose of this phase is to determine how and when the project could be constructed. In February 2018, ODOT will present methods and cost to construct improvements along I-205 and discuss the potential of moving forward with this project. ODOT currently has funding to complete preliminary design. Funding discussions regarding final design and construction will occur with the Oregon Legislature in the 2018 Legislative Session, which begins in February 2018. Keep checking back here for updates.

What are the issues?

  • The two-lane section of I-205 between the Abernethy Bridge and the Stafford Road interchange creates a bottleneck that causes congestion and crashes, creating delays for travelers and freight.
  • Closely spaced on-ramps on I-205 northbound on the Abernethy Bridge contribute to safety and travel-time predictability issues.
  • The Abernethy Bridge and eight bridge sites in the project area are seismically vulnerable in the event of a major earthquake.

What are the solutions?

  • Adding a third lane on I-205 in each direction between Stafford Road and OR 99E will improve traffic operations and reduce vehicle crashes. The improvements will make I-205 a consistent three-lane interstate in each direction from the Columbia River to I-5.
  • Seismically upgrading the Abernethy Bridge and all other I-205 bridges within the project limits ensures the corridor functions as a statewide north-south lifeline route after a major earthquake.
