3rd Ave and Denny Way Signal Improvements

July 1, 2021

This project is complete.

Project Description

This project will improve transit operation and accessibility from northbound 3rd Ave to westbound Denny Way through:

• Modifying signals at 1st Ave and Denny Way, 2nd Ave and Denny Way, and 3rd Ave and Broad St
• Updating existing transit trolley poles and rewiring trolley lines
• Modifying the triangular block between 3rd Ave, Broad St, and Denny Way
• Install new signal at 3rd Ave and Denny Way

A large part of this project is reconstructing the triangular block between 3rd Ave, Broad St, and Denny Way. The new block of 3rd Ave between Broad St and Denny Way will become 2-way with northbound for transit only and southbound continues to serve general traffic. The new design will also include some changes to the curb line and a new transit only signal.

We are working with King County Metro to coordinate updating the existing trolley poles and rewiring the trolleys to new poles.
