SR 99 lane restrictions to begin Monday, April 22 as part of Mercer Corridor Project

Posted on Apr 15 2013 11:38 AM

The Seattle Department of Transportation (SDOT) advises travelers of SR 99 lane restrictions beginning Monday, April 22, associated with the West Phase of the Mercer Corridor Project. These lane reductions are one of the first steps in beginning Mercer West construction and will allow crews to complete early preparatory work associated with rebuilding the SR 99 Aurora overpass over Mercer Street.

 

SR 99 Lane restrictions

On Monday, April 22, following the morning commute, crews will begin reducing SR 99 to two lanes in each direction between Aloha and Harrison streets:

The curb lane on southbound SR 99 will be restricted between Aloha and Harrison streets.

The curb lane on northbound SR 99 will be restricted between the Mercer Street exit and Roy Street.

These curb lane restrictions accommodate early construction work associated with Mercer West and rebuilding the SR 99 Aurora overpass over Mercer Street.

Sidewalks on SR 99 will also be impacted during this work. The sidewalk on the west side of SR 99 will be closed between Thomas Street and Roy Street and the sidewalk on the east side of SR 99 will be closed between Republican Street and Roy Street.

 

Lane reductions on SR 99 will continue throughout the West Phase of the Mercer Corridor Project anticipated to be complete in mid-2015. 

Additionally, the Broad Street off-ramp from southbound SR 99 will be closed at the same time and will remain closed through the duration of Mercer West construction.

Early warning signs will be available in advance of the SR 99 lane restrictions. Travelers can expect significant traffic and delays and should plan ahead and use alternate routes when possible.
