Beginning as early as Monday, Jan. 6, Seattle Department of Transportation (SDOT) crews will close westbound West Mercer Street between Fourth and Fifth avenues West to accommodate deep drainage work.

During this work, travelers can expect the following impacts:

•Westbound West Mercer Street between Fourth and Fifth avenues West will fully close beginning the morning of Monday, Jan. 6, through the morning of Friday, Jan. 10.

•Westbound traffic on West Mercer Street will detour south on Fourth Avenue West and then westbound on Harrison Street to reconnect to Elliott Avenue West. (More information about alternate routes during construction may be found at www.seattle.gov/transportation/mercercorridor.htm.)

•Travelers heading toward the Elliott Avenue West and 15th Avenue West corridor from Interstate 5 should use Broad Street and Denny Way or Ninth/Westlake avenue North and Nickerson Street as alternate routes.

Eastbound traffic on West Mercer Street will be maintained at all times.

Work hours will be between approximately 7 a.m. and 4 p.m. (this work is weather-dependent and may be rescheduled in the event of inclement weather).

Also, beginning the evening of Monday, Jan. 6, eastbound Mercer Street between Fifth and Dexter avenues North will fully close to traffic at night for approximately two weeks as crews install lateral storm-water connection lines under the roadway. Nighttime closures will be in effect from 9 p.m. to 5 a.m. weekday evenings.

During this work, travelers can expect:

•Traffic on eastbound Mercer Street will need to turn right on Fifth Avenue North and reconnect to eastbound Mercer Street via Harrison and eastbound Broad streets.

•Northbound and southbound Fifth Avenue North will remain open to traffic.

•Access to Mercer Street from southbound Fifth Avenue North will be via Harrison and eastbound Broad streets.

•The sidewalk on Mercer Street will also close between Fifth and Dexter avenues North. Pedestrians will detour to Broad Street.

Due to multiple high-volume nighttime events at the Seattle Center during these two weeks, travelers should plan ahead and use alternative routes.
