We’ve said it was coming but that doesn’t make it any easier…11PM tonight through 5AM Monday, May 20 FULL CLOSURE OF:
- SR 99-Valley Street to the southern end of the Battery Street Tunnel
- Mercer Street-Fifth Avenue N to Dexter Avenue N
Sidewalks will be closed on both sides of SR 99 between Thomas and Valley Streets, and on the south side of Mercer Street between Fifth Avenue N and Dexter Avenue N.
That isn’t the worst of it, because we are really just beginning this segment of the Mercer Corridor effort – meaning MAJOR impacts are beginning.
Following the full weekend closure of SR 99, lane restrictions on Mercer Street will remain in place between Fourth Avenue N and Ninth Avenue N.

To help alleviate traffic congestion on eastbound Mercer Street, eastbound Broad Street will re-open to traffic on Monday, May 20, as an alternate route for travelers heading to I-5. Additional traffic revisions will include:
- Mercer Street between Fourth and Ninth avenues north down to two eastbound lanes (local access maintained at Taylor Avenue N)
- Sidewalk on the north side of Mercer Street closed between Fifth Dexter avenues north (sidewalk on the south side of Mercer Street will remain open)
- SR 99 traffic between Valley and Harrison streets shifted to the west side of the roadway (two lanes of SR 99 in each direction will remain open)
The northbound SR 99 off-ramp to Mercer Street will be permanently closed. A new signalized intersection at Republican Street and Dexter Avenue N will be available for northbound SR 99 traffic to reach South Lake Union.
OK, that’s all for now, but it really seems like enough…
