Project overview

The Seattle Department of Transportation is improving 7th Ave between Westlake Ave and Union St by extending the protected bike lane and updating traffic signals and circulation. Planned improvements include:

  • Adding curb bulbs to shorten pedestrian crossings
  • Extending the 1-way southbound protected bike lane on the west side of 7th Ave from Westlake Ave to Pike St and adding a bike "sharrow" between Pike and Union streets to better connect South Lake Union and Capitol Hill/downtown
  • Upgrading traffic signals and converting the "contraflow lane" between Olive Way and Pine St from northbound to southbound to improve circulation

See cross sections below showing the planned layout at various locations.

Why 7th Ave?

The project began as part of the Center City Bike Network project to study downtown streets and determine which would be the best fit for protected bike lanes.

Vision Zero Logo 7th Ave was selected because it extends the existing 7th Ave protected bike lane and serves as an intuitive connection between South Lake Union and Capitol Hill. The route also has relatively low vehicle traffic volumes compared with other downtown streets and doesn’t serve transit riders. In addition, the conversion of 1 block from 2-way to 1-way provides an opportunity to improve traffic flow.

Extending the 7th Ave protected bike lane is part of the City’s Vision Zero plan to end traffic deaths and serious injuries by 2030.

Project area

The future protected bike lane will be on 7th Ave between Virginia and Pike


7th Ave Mobility Improvements is funded by a combination of local and federal matching funds.


Preliminary construction to locate utilities began in October 2017. Crews expect to complete more substantial construction from early 2018 to spring 2018.We expect construction to begin in late summer 2017 and to last through early 2018.
