Project overview

Coming changes

We are making traffic signal improvements and extending the existing 2-way protected bike lane along 2nd Ave from Pike St to Denny Way. These improvements will organize the street and move people more efficiently.

There are 3 key features of the project:

  1. Extending the 2nd Ave protected bike lane. Similar to the existing protected bike lane on 2nd Ave, SDOT will continue a 2-way protected bike lane on the east side of 2nd Ave located between the parking/turn lane and the sidewalk.
  2. Adding 3 new traffic signals. The project will add 3 new traffic signals at Cedar, Clay, and Vine streets which will make for safer turns on and off 2nd Ave and will make it easier for people to cross 2nd Ave.
  3. Making traffic signal upgrades. Signals will be upgraded with left turn pockets and a designated phase for drivers to turn left that is separate from people walking and biking.

This project is part of the City's Vision Zero plan to end traffic deaths and serious injuries by 2030. The improvements also contribute to SDOT's goal to provide people who live, work, and play in Seattle with multiple travel options depending on their needs.



The City procured a $5 million federal grant for the project. This project is also funded by the 9-year Levy to Move Seattle, approved by voters in 2015.
