The Seattle Department of Transportation is working within the Mercer Corridor Project area on Saturday, March 15, causing several related closures.

Between 4 a.m. and 6 p.m., northbound Dexter Avenue North between Roy and Valley streets will fully close to accommodate utility work beneath the roadway.

Travelers heading north toward Fremont should use Ninth or Westlake avenues North.

Southbound Dexter Avenue North will be restricted to one lane between Valley and Mercer streets.

Uniformed police officers will be stationed throughout the work zone to facilitate traffic flow.

Early warning signs will be available in advance of Dexter Avenue North detours. Travelers can expect delays and should plan ahead and use alternate routes.

Between 4 a.m. and 6 p.m., eastbound Mercer Street will be restricted to one lane between Fifth and Dexter avenues North to accommodate utility work beneath the roadway.

During the closure, one eastbound lane on Mercer Street will remain open at all times.

Travelers heading east from Fifth Avenue North should take Harrison Street to eastbound Broad Street to reconnect with Mercer Street at Ninth Avenue North as an alternate route. 

More information about alternate routes during construction may be found at www.seattle.gov/transportation/mercercorridor.htm.
