Road Construction & Seattle Center
SR 520 and Alaskan Way Viaduct Update
Mercer Corridor Project
Road construction associated with the Mercer West project is substantially complete, and North Portal construction related to the SR-99 viaduct and tunnel, is ongoing. The tunnel boring machine is expected to reach the north end of the SR-99 tunnel in early June, and the tunnel is expected to open in early 2019.
Please consider the following as you route your way to and from Seattle Center, and allow extra time in your travels during this critical period of transition on our roadways. If roads around the Mercer corridor are congested, consider other options to access I-5 and SR-99 using entry points south of Seattle Center, along 2nd Ave. and 5th Ave. 

Until SR-99 Tunnel opens to traffic: 6th Ave N is closed between Thomas and Republican streets. Republican St. is closed between Aurora Ave. N and 6th Ave N.

Tuesday, Feb. 7, mid-afternoon to 10pm: Expect increased congestion around Seattle Center during the evening commute and again later in the evening from WWE Smackdown, 4:45pm-9pm, at KeyArena.

Through Friday, Feb. 10, 24/7:  Thomas St. is closed between Aurora Ave. N. and 6th Ave. N.

Friday, Feb. 10 at 11pm to Monday, Feb. 13 at 5am: Westbound I-90 will be reduced to one lane and diverted into the center roadway between Bellevue and Seattle. 

Friday, Feb. 17:  a noon march from Volunteer Park to Myrtle Edwards Park will traverse along Denny Way. Walkers are expected to arrive at Elliott Bay by 2:30pm.

Saturday, Feb. 18 or Sunday, Feb. 19, 5am-9pm: Southbound SR-99 is closed between Valley and Thomas streets for road restriping.

Saturday, March 4 and Sunday, March 5, 6am to 6pm:  SR-99 will close in both directions between S. Spokane St. and the Battery Street Tunnel for its semi-annual inspection.  

Elliott Bay Seawall Project: Seawall project construction has moved north to between Virginia and Pine streets and adjacent to Pier 62/63. Work between Pine and Union streets wrap up in the early part of this year.

Staging for this work stretches from Lenora St. to Pike St. Daytime and evening construction will occur. Sidewalk access will be restricted along the west side of Alaskan Way. As part of Waterfront Seattle, construction of the Pier 62/63 Rebuild Phase 1 is expected to begin soon.
