Project Background

Providing sidewalks and bike lanes on this segment of SW Capitol Highway has been a community priority for more than 20 years. This segment, between SW Garden Home Road and SW Taylors Ferry Road, hosts over 8,000 vehicles per day, is served by TriMet’s #44 bus line, and currently has no sidewalks, bike lanes, pedestrian crossings or standard stormwater facilities.The City’s project development process for this corridor began with the Capitol Highway Plan in 1996 and continued with the SW Capitol Highway Plan Refinement Report in 2011 and the Capitol Highway Corridor Stormwater Concept Design in 2016. In each of these cases, the City faced challenges in developing a buildable project with limited funding and challenging physical constraints. Now, with Fixing Our Streets funds available to leverage other funding from PBOT and Environmental Services, the City can move forward. The project is the single largest enhancement project funded by the Fixing Our Streets gas tax approved by voters in May 2016.

As soon as funding was secured, PBOT staff gathered input on this long-awaited project from the Southwest Portland community, including a July 30 neighborhood walk hosted by the Multnomah Neighborhood Association (MNA) and several meetings with the MNA Capitol Highway Subcommittee and the Southwest Neighborhoods, Inc. (SWNI) Transportation Committee. PBOT also released a series of cross section concepts in fall 2016 for public comment and presented these concepts to the city’s Pedestrian Advisory Committee and Bicycle Advisory Committee.

PBOT developed a preferred roadway cross section concept based on this feedback and past planning efforts including the 2011 SW Capitol Highway Plan Refinement Report and the 2016 Capitol Highway Corridor Stormwater Concept Design. Available funding is not sufficient to provide complete sidewalks and bike lanes on both sides of the roadway, so the proposed cross section includes compromises that provide safe, functional facilities at lesser cost.

Community feedback revealed a strong preference for continuous sidewalk on the east side of the roadway to access the viaduct to Multnomah Village and the walking route to Barbur Transit Center, and this has been incorporated into the design. Continuous bikeways in both directions are also proposed, including a northbound “protected” bike lane separated from the roadway by a planter strip of low shrubs and occasional stormwater facilities. An earlier proposed buffered bike lane was removed from consideration based on comments preferring additional protection from motor vehicles, which is also consistent with city and national  design guidance for bike lanes on major roadways. On the steeper west side of the roadway, a separated multi-use path is proposed to host southbound bicycling and bi-directional walking.

Environmental Services will partner on stormwater management efforts along the roadway, and look for opportunities to improve drainage issues in adjacent neighborhoods within the four basins (see map) in the project area. The project, which is early in the design stage, may include features such as neighborhood stormwater facilities, green streets, ditch enhancements, and underground infrastructure.

The project design will continue to be refined through the end of 2018. Construction will begin in 2019.
