[Editor's note: As of Friday, April 4, the Seattle Department of Transportation has canceled its weekend closure of eastbound Mercer Street between Dexter and Ninth avenues North due to anticipated inclement weather. The work at Queen Anne Avenue North and Roy Street will still occur.]

 

The Seattle Department of Transportation (SDOT) advises travelers of construction activities within the Mercer Corridor Project area this weekend. Travelers can expect significant traffic and delays and should plan ahead and use alternate routes.

To accommodate paving activities, beginning the evening of Friday, April 4, at 11 p.m., through Monday, April 7, at 5 a.m., both eastbound Mercer Street between Dexter and Ninth avenues North and Ninth Avenue North between Mercer and Republican streets will fully close to traffic. 

While eastbound Mercer Street is fully closed to traffic between Dexter and Ninth, travelers heading east on Mercer Street should take southbound Fifth Avenue North to Harrison Street and eastbound Broad Street to reconnect with Mercer Street (more information about alternate routes during construction may be found at www.seattle.gov/transportation/mercercorridor.htm).

During the closure of Ninth Avenue North between Mercer and Republican streets, travelers heading southbound on Ninth will need to turn left onto eastbound Mercer Street and use southbound Westlake Avenue North to reach the city center.

Traffic on Dexter will be maintained in both directions at all times.

The Interstate 5 ramps at Mercer Street, westbound Mercer Street and Broad Street will remain open during this work.

Access to the Seattle Center from I-5 via westbound Mercer and Broad streets will open through the weekend, but travelers should expect delays.

This work is weather-dependent and may be rescheduled in the event of inclement weather.

Also, from Saturday, April 5, at 4 a.m., through Monday, April 7, at 5 a.m., access to northbound Queen Anne Avenue North will fully close to traffic from Roy Street to accommodate signal-pole installations and sidewalk work. 

While access to northbound Queen Anne Avenue is closed to traffic from Roy Street, travelers heading north from westbound Roy Street will detour onto southbound Queen Anne Avenue and then right onto Mercer Street to proceed north on Second Avenue West. 

To access Queen Anne from downtown, travelers should use westbound Mercer Street to Second Avenue West or Fifth and Taylor avenues North.

Southbound Queen Anne Avenue will reduce to one lane between Valley and Roy streets. One lane of southbound traffic will be maintained at all times.

Turns from eastbound Roy Street onto Queen Anne Avenue will also be restricted.

Uniformed police officers will be present to facilitate traffic flow around the work zone.

Early warning signs will be available in advance of all detours.
