(Aug. 16, 2021) As work progresses on the SW Capitol Highway: Multnomah Village to West Portland project, the Portland Bureau of Transportation (PBOT) advises that a southbound detour of SW Capitol Highway will begin on Wednesday, Aug. 18. The detour will remain in effect until as late as November 2022.

When complete, SW Capitol Highway between SW Garden Home and Taylors Ferry roads will be a transformed street with new sidewalks, bike lanes, pavement, stormwater management, and a new water main.

As construction continues on the corridor, only northbound traffic will be allowed on SW Capitol Highway between SW Taylors Ferry Road and SW Garden Home Road.

All southbound traffic coming over the bridge from Multnomah Village on SW Capitol Highway will be diverted westward on SW Garden Home Road, southward on SW 45th/48th Avenue/Drive, and eastward on SW Taylors Ferry Road back to SW Capitol Highway. Pedestrians will be able to walk in both directions on SW Capitol Highway but may encounter temporary delays or reroutes.

As part of the detour, TriMet bus lines 44 – Capitol Hwy/Mocks Crest and 64 – Marquam Hill/Tigard will be detoured off SW Capitol Hwy in the southbound direction starting Sunday, August 15. Buses will travel the detour route described above. Southbound stops on SW Capitol Highway between Garden Home and Taylors Ferry will be closed and temporary stops will be located along the detour. There will be no changes to the northbound route towards Portland/Marquam Hill, other than occasional closures of individual stops on the east side of the street.

People riding transit should visit www.trimet.org/#alerts/ for the latest service impacts.

Providing sidewalks and bike lanes on this segment of SW Capitol Highway has been a community priority for nearly 30 years. The project area, between SW Garden Home Road and SW Taylors Ferry Road, hosts over 8,000 vehicles per day, currently has no sidewalks, bike lanes, pedestrian crossings or standard stormwater facilities.

In 2016 and 2017 sufficient funding came together from the voter-approved Fixing Our Streets ten-cent gas tax, development charges, Environmental Services, Water Bureau, and the State of Oregon, allowing the project to advance. The project team worked closely with the community from 2016 through 2020 to refine the design and discuss property and neighborhood impacts and benefits. 

PBOT greatly appreciates the patience and understanding of nearby residents, businesses and those who will be traveling through the area.

We ask the public to travel slowly and cautiously in our work zones, observe all detours and directions by reader boards and flaggers, and use alternate routes if possible. Expect dust, noise, vibrations, and heavy equipment on SW Capitol Highway and side streets. As always, please keep our crews safe by following all traffic control signs and flaggers while travelling through or near work zones.

Thank you for your cooperation and patience while we complete this work.
