I-205 Paving & Auxiliary Lanes

Johnson Creek Boulevard to the Glenn Jackson Bridge


Approximately nine miles of I-205 will be repaved in both directions between Johnson Creek Boulevard and the Glenn Jackson Bridge, including many freeway ramps. This section of freeway was last paved in 2004. The surface is deteriorating and needs to be replaced.

Paving will take place mostly at night, with lane closures on I-205. Multiple overnight closures will take place on several I-205 on-ramps and off-ramps in the project area. There will also be lane closures on cross-streets near on-ramps and off-ramps.

Auxiliary lanes

Lanes extensions from entrance to exit ramps will improve safety at these locations:

  • I-205 southbound from I-84 eastbound to the southbound Division/Powell on-ramp
  • I-205 northbound from Powell Boulevard to I-84 westbound
  • I-205 northbound from I-84 eastbound to the Killingsworth Stree exit

Auxiliary lanes will improve safety and reduce congestion on I-205 and surrounding roads. Works will take place during the day and at night and will require lane and shoulder closures.

Sidewalk curb ramp improvements

Many intersections near I-205 on-ramps and off-ramps will receive improvements to make them ADA-compliant.

Traveler information and advisory signs

New electronic signs, called ODOT RealTime signs, will be installed throughout the project area to display traffic flow and roadway conditions, enabling drivers to make informed travel decisions.

Anticipated project schedule

Design Phase: Summer 2015 – Fall 2018

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.

Auxiliary lanes

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.

Auxiliary lanes will improve bottlenecks on I-205

The Corridor Bottleneck Operations Study found areas on I-205 within this project area where auxiliary lanes could improve safety and reduce recurring congestion. An auxiliary lane typically provides a direct connection on the freeway from one interchange ramp to the next. These “entrance-to-exit” lanes reduce the conflicts
that cause congestion and crashes, by separating slower movements from the freeway mainline. Diagrams and benefits of the new auxiliary lanes are outlined below and on the following page.

Southbound auxiliary lane

I-84 Eastbound to Division Street/Powell Boulevard

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 Street 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.

Northbound auxiliary lane

Powell Boulevard to I-84 Westbound

High traffic volumes and short merging distances in this area currently cause speeds to drop to 10—15 miles per hour during peak travel times. I-205 experiences many high-crash sites in this area. This entrance to exit lane will provide a safer connection for I-205 traffic bound for Stark Street/Washington Street, Glisan Street, and I-84 westbound.

Northbound auxiliary lane

I-84 Eastbound to Killingsworth Street

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 address 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 and I-205 traffic bound to Sandy Boulevard or Killingsworth Street. This will improve safety and operations for freight movement.
