SW Barton St Layover Repaving

Updated March 19, 2026

What are we doing and why?

If you travel on SW Barton Street near the Westwood Village shopping center, you’ve probably seen the big cracks and bumpy concrete. This happens because the ground under the street is sinking, which makes the concrete sink too. The heavy buses that park there at the end of their routes make the problem worse. Our crews try to fix this by adding asphalt, but those patches don’t last long and make the street bumpier and noisier. 

Now, with King County Metro's help, we are working to fix the street for good. They will replace the ground under the street with a lighter material and repave it with stronger concrete that can handle the weight of buses. 

Here’s how this helps you: 

• The street will stay in better shape and need fewer repairs
• Buses will have fewer problems, which saves money
• Your rides—whether in a car, on a bus, or on a bike—will be smoother and quieter

This project will make it easier and safer for everyone to get to and through Westwood Village. 

When are we beginning this project?  

Construction expected to begin: April 2026

How will this affect you? 

Part of SW Barton will be closed during construction so that we can do our work. You can expect some bus stops and the layover zone to shift to a new location and some bus routes to change (temporarily) during construction. See the changes below: 

Route 21 & Rapid Ride C-Line to Westwood Village

Route 21 buses heading toward Westwood Village (southbound) will turn from 35th Ave SW onto SW Trenton St. The bus will continue traveling east on SW Trenton St, with three more stops:

1. SW Trenton St east of 35th Ave SW
2. SW Trenton St at either 29th or 30th Ave SW
3. SW Trenton St just west of 25th Ave SW, on the north end of Westwood Village 

C-Line buses will turn off SW Barton to travel north on 35th Ave SW, then turn onto SW Trenton St to travel east. The bus will continue travelling east on SW Trenton St, with three stops: 

1. 35th Ave SW and SW Trenton St
2. Between 29/30th Ave SW Trenton St
3. The last stop will come after turning southbound on 25th Ave SW, just south of SW Henderson St. 

Leaving Westwood Village on the Rapid Ride C-Line or Rt. 21 

Catch the Rapid Ride C-Line or Rt. 21 bus toward downtown Seattle at the southbound bus stop on 25th Ave SW just north of SW Barton St (at the southeast corner of Westwood village):

If you are:   

• Driving your car - at least one lane of the street will remain open during construction. You will also be able to enter the Westwood Village shopping center will remain open.
• Walking or rolling on the sidewalk - you will not be able to travel on the sidewalk next to Roxhill Park during construction.
