I-205 Paving & Auxiliary LanesJohnson Creek Boulevard to Glenn Jackson Bridge
About the project
The Oregon Department of Transportation is currently in the planning and design phase for a project to improve operations and safety on I-205 between Johnson Creek Boulevard and Glenn Jackson Bridge. Two auxiliary lanes will be built to significantly relieve recurring congestion and reduce crashes. In addition, I-205 will be paved in both directions and many intersections and ramps will be paved and improved.
Construction will take place in 2018 and 2019. Work will mostly take place at night, with lane closures on I-205. Multiple overnight closures will take place on I-205 on- and off-ramps in the project area. There will also be lane closures on cross-streets near on- and off-ramps.
Anticipated project schedule
Design Phase: Summer 2015 – Summer 2017
Construction: Early 2018 – Late 2019
Dates are subject to change. There will be construction and traffic impacts as part of this project; more information will be available prior to construction.

Approximately nine miles of I-205 will be repaved in both directions between Johnson Creek Boulevard and Glenn Jackson Bridge, including many freeway ramps. The surface is deteriorating and needs to be replaced. This section of freeway was last paved in 2004.
Improving highway bottlenecks to address safety and reduce congestion
The Federal Highway Administration has found that approximately 40 percent of all congestion nationwide can be attributed to recurring congestion – or “bottlenecks.” In 2009, ODOT started a new approach to deal with recurring localized freeway bottlenecks in the Portland metro area. The Corridor Bottleneck Operations Study identified areas of recurring congestion along five key Portland metro area highways (I-5, I-205, I-84, I-405 and US 26) and recommended low-cost, highly effective solutions to improve safety and reduce congestion at these locations. In many cases, auxiliary lanes were the recommended solution.
What is an auxiliary lane?
An auxiliary lane typically provides a direct connection on the freeway from one interchange ramp to the next. The purpose is to allow the mixing of different traffic speeds that are entering and exiting the freeway. The lane separates the slower movements from the freeway mainline, reducing conflicts that cause congestion and improving safety and traffic flow at the freeway interchanges.
Auxiliary lanes will improve bottlenecks on I-205
The Corridor Bottleneck Operations Study found two areas on I-205 within this project area where auxiliary lanes could improve safety and reduce recurring congestion. A northbound auxiliary lane will provide a direct connection between the I-84 eastbound interchange, the I-84 westbound interchange, the Sandy Boulevard exit and the Killingsworth Street exit. A southbound auxiliary lane will provide a direct connection from the I-84 eastbound interchange to the Division Street / Powell Boulevard exit. Peak time speeds will be significantly improved and crashes are expected to reduce by at least 30 percent.
Northbound auxiliary lane
High traffic volumes and short merging distances on I-205 currently cause speeds to drop below five miles per hour during peak travel times. This auxiliary lane will fix multiple bottlenecks and improve traffic flow along the northern portion of I-205. The auxiliary lane provides more room for vehicles to merge and provides a connection for I-84 traffic bound to Sandy Boulevard or Killingsworth Street. This will improve safety and operations for freight movements.
Southbound auxiliary lane
Approximately 25 percent of I-205 southbound traffic coming from I-84 eastbound is bound for the Division/Powell exit. The new auxiliary lane will provide a connection from this interchange to the Washington/Division/Powell entrance and connect with the existing auxiliary lane that continues to the Division/Powell exit. The auxiliary lane will require less weaving and merging, reducing congestion in all lanes. This project is expected to reduce crashes in the area by 30 percent.
