SW Barton St Layover Repaving

Updated February 3, 2026

What are we doing and why? 

SW Barton Street (near the Westwood Village shopping center), is full of large cracks, and the concrete is buckling in several areas. This is happening for a few different reasons. First, the soil underneath the road is settling and causing the concrete above to sink. Second, the weight of the buses has worsened this damage, especially in the bus layover zone where buses park at the end of their routes. Crews add asphalt to the street wherever they can, but these temporary fixes lead to louder, bumpier rides.  

With help from King County Metro, we plan to repave this street so that it can handle the weight of all the buses that travel on it. We will replace the soil underneath with lightweight cellular concrete. Then, we will repave the road with concrete designed to handle the weight of so many buses. Taking these measures to repave the road will:  

• Reduce maintenance costs for keeping SW Barton St in good repair
• Lower maintenance costs for buses
• Make for smoother driving and less damage to Metro buses and other vehicles 

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 routes to change (temporarily) during construction. See the changes below: 

Route 21 to Westwood Village

Route 21 buses leaving Westwood Village (southbound) will turn from 35th Ave SW onto SW Trenton St.   

The bus will continue traveling eastbound 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 

Rapid Ride C-Line to Westwood Village

C-Line buses will turn off SW Barton onto 35th Ave SW (northbound), then travel eastbound on SW Trenton St. 

The bus will continue travelling eastbound 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 Av SW just north of SW Barton St (at the southeast corner of Westwood village):

If you are driving a car in the area - 

• Roads will remain open for at least one lane at a time during construction. Access to driveways to the Westwood Village shopping center will remain open.

If you are walking or rolling on the sidewalk - 

• The sidewalk next to Roxhill Park will be closed during construction.
