Mercer Corridor Project reminder for Memorial Day weekend

The Seattle Department of Transportation reminds travelers that Mercer Street is now fully operational for westbound as well as eastbound traffic between Fifth Avenue North and Elliott Avenue West.

Mercer Corridor Project crews are not scheduled to work over the holiday weekend, although SDOT asks all travelers, including pedestrians, to please pay attention to street signs as traffic patterns within the corridor have recently changed. Over Memorial Day weekend, you can expect the following conditions throughout the corridor:

  • Mercer Street open to two-way traffic between Elliott Avenue West and Fifth Avenue North.
  • Roy Street reduced to one westbound lane between Queen Anne Avenue North and Fifth Avenue North.
  • Mercer Street remains eastbound-only between Fifth Avenue North and Ninth Avenue North with two lanes open to traffic.


Two-way traffic on Mercer Street, Roy Street and Queen Anne Avenue N scheduled to open in early June

The final phase of work associated with opening Mercer Street between Fifth Avenue North and Ninth Avenue North, Roy Street between Fifth Avenue North and Queen Anne Avenue North, and Queen Anne Avenue North between Mercer and Roy streets to two-way traffic, and closing Broad Street, is anticipated to occur the weekend of May 31 – June 2. Details about construction activities and associated closure information for this weekend will be announced in the near future.


Reminder: Broad Street will close permanently in early June

With the opening of two-way traffic on Mercer Street, Broad Street will permanently close to traffic in both directions between Fifth Avenue North and Ninth Avenue North to allow for additional space to widen Mercer Street to the south at Dexter Avenue North and work associated with the Alaskan Way Viaduct Replacement Project.
