Mercer Corridor Project, SR 520 and Alaskan Way Viaduct Update
Mercer Corridor Project

We are in an active period of road construction around Seattle Center (and in the region). Travelers are experiencing MAJOR CORRIDOR CHANGES associated with the Mercer Corridor Project.

Please take into account 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.


*  Mercer St. is fully open to two-way  traffic between I-5 and Elliott Ave. W.
*  Roy St. is open to two-way traffic between 5th Ave. N. and Queen Anne Ave. N.
   IF YOU EXPERIENCE TRAFFIC CONGESTION ALONG MERCER, please consider Roy St. as an      alternative route. Queen Anne Ave. N. is open to two-way traffic between Roy St., and Mercer St. 
*  Broad St. between 5th Ave. N. and Mercer St. is CLOSED permanently.

5th Ave. N. Garage:  Harrison St. and Republican St. entrances/exits remain open, with access from northbound and southbound 5th Ave. N.

Mercer Garage:  3rd Ave. N. and 4th Ave. N. entrances/exits remain open (4th Ave. open for events only), with a designated left turn lane from eastbound Mercer St. onto 4th Ave. N.
Through Friday, Aug. 22, 9pm - 5am nightly:  Dexter Ave. N. between Thomas and Mercer streets is closed in both directions. Republican St. between Dexter and SR-99 is also closed.

Beginning on Friday, Aug. 22, 9am - 3pm daily:  the right turn lane from northbound 5th Ave. N. to eastbound Mercer St. will be closed.  
Through Fall 2014: Only one lane in each direction of Dexter Ave. N. between Thomas and Roy streets remains open. Harrison St. is closed between SR 99 and 8th Ave. N. A separate bike lane is maintained on Dexter Ave. N. during peak commute hours. Cyclists might be directed to merge with traffic during off-peak hours. Street  parking is closed in the work zone, and Metro bus stops are relocated to near Thomas St.
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. More information about alternate routes during construction may be found at: http://www.seattle.gov/transportation/mercercorridor.htm
