Columbia St paving & striping this week.

Street work on Columbia St.

The Columbia St 2-way Transit Corridor Project will complete its last segment of paving work on Columbia St between 1st and 2nd Avenues this Thursday. We’ll return to the project site this Saturday to complete striping work on Columbia St between 1st and 3rd Avenues. Both will require temporary lane restrictions.


What you can expect.

About the project.

Today, Columbia St is a 1-way street heading westbound that connects to a viaduct on-ramp at 3rd Ave. Our project – the Columbia St 2-way Transit Corridor – will rebuild the segment between 1st Ave and 3rd Ave. The segment between 3rd Ave and Alaskan Way will be rebuilt and converted to 2-way operations as part of the Waterfront Seattle project. Once done, there will be a new cement street that can handle the higher weight of buses and an eastbound lane for transit and local access to move thousands of people a day into downtown Seattle on our new, post-viaduct transit pathway.
