3rd Ave Belltown Paving Project (Virginia St to Broad St)

3rd Ave Paving Project

What's happening now?

Paving between Blanchard and Battery streets: This area is the last section of major paving across the corridor. Crews have shifted work to the center lanes on either side of the Bell St intersection, and will begin pouring new concrete as early as Friday, November 17. To accommodate this work:
  • Southbound 3rd Ave traffic will be rerouted to 5th Ave between Battery and Lenora streets 7 AM-5 PM daily Friday, November 17 through Wednesday, November 22. The reroute will not be in effect on Sunday, November 19. A single lane of northbound 3rd Ave traffic will be maintained. See detour map below. For information on changes to Metro routes and stops, please visit http://kingcounty.gov/metro/alerts.
  • Daytime paving on Saturday, November 18 during normal hours (7 AM - 5 PM so crews can complete paving in a timely manner
  • No construction activities on Thursday, November 24 or Friday, November 24 for the Thanksgiving holiday  
Ongoing side street closures (through early December):
  • Blanchard St between 2nd and 3rd avenues
  • Bell St between 3rd and 4th avenues  

Ongoing minor electrical, pavement, and sidewalk repairs: Crews will continue to perform minor repairs along the entire project corridor through the end of the project, including curb ramp upgrades at the intersections of Wall, Vine, and Clay streets.

Construction overview

To minimize the duration of the work in front of a given property or block, we divided the project area into 4 work zones. Crews have completed major construction in one zone before moving to the next:

  • Zone A: Virginia St to Blanchard St (major construction complete)
  • Zone B: Blanchard St to Battery St (crews are working here now)
  • Zone C: Battery St to Vine St (major construction complete)
  • Zone D: Vine St to Broad St (major construction complete)

3rd Ave will generally remain open to traffic throughout construction, although it will be reduced to a single lane in each direction in the active construction zone. Occasional detours are expected and will continue to be communicated in advance. On-street parking will be restricted temporarily at construction locations.

Weekend work will be necessary at intersections heavily used by Metro during the week. Other construction will occur during standard work hours (Monday through Friday, 7 AM – 5 PM). SDOT is working closely with King County Metro so buses continue to operate during construction, although individual bus stops will be temporarily closed or moved. We will not simultaneously close bus stops next to one another.

Project overview

3rd Ave through Belltown is a primary arterial carrying some 3,600 vehicles per day, approximately 45% of which are buses. Currently, the street has many potholes and patches from previous cuts into the pavement to install utilities.

Prior to this project, the street was composed of a mix of concrete panels and asphalt. We are removing all asphalt and replacing it with concrete panels, which last longer than asphalt. We are also replacing concrete panels in the existing curb lane where needed, specifically broken panels and/or those that have previously been cut into for repairs or utility service connections (which makes them more susceptible to breaking).

In addition to repaving the street, the project includes:

  • Replacing curb ramps at some intersections to bring them into compliance with the Americans with Disabilities Act (ADA). Sidewalks will otherwise not be impacted.
  • Replacing and/or repairing sections of water mains and sewer lines
  • Installing electrical conduit at select locations
  • Expanding both the northbound and southbound bus zones at Virginia St in order to better accommodate the large number of buses using these stops


Construction began May 2, 2017 and take approximately 10 months to complete, with major paving completed this year.  We will update this page as construction progresses.
