7th Ave Mobility Improvements


Developer Christian Gunter explains why protected bike lanes and other transportation infrastructure are important for a growing city.

What's happening now?

Crews began construction to improve 7th Ave between Westlake Ave and Union St on January 2, 2018. We expect construction to last through April 2018. Crews are working on the project from north to south, with the work area stretching approximately 2-3 blocks at a time. Neighbors should expect typical weekday work hours from 7 AM - 5 PM, temporary lane closures on 7th Ave, potential traffic delays, and intermittent night and weekend work.

Olive Way to Pine St

Crews will temporarily detour northbound 7th Ave traffic to 6th Ave at Pine St on January 26 and January 27 while maintaining access to all destinations on the block. Crews will maintain 2-way traffic between Olive Way and Pine St during peak travel periods on Friday (before 9 AM and between 3-6 PM), but travelers should expect lane reductions, potential travel delays, and overnight work on Friday.

Stewart St intersection

Crews plan to work at the 7th Ave and Stewart St intersection on Saturday, January 27. Traffic will be maintained through the intersection, but there may be lane shifts and temporary delays.

These activities are weather-dependent and subject to change.

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

Funding

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