Advisories from the Seattle Department of Transportation

Mercer Ramp Closures this Weekend

by

Seattle Department of Transportation (SDOT) reminds travelers of the upcoming  January 13 – 16 weekend closure of the I-5 on- and off- ramps at Mercer Street. Closure hours are scheduled for Friday at 11:00 p.m. to Monday at 5:00 a.m.

During this closure, crews will prepare for Stage 2 of Mercer East by switching eastbound Mercer Street traffic onto the new Mercer Street lanes north of the existing lanes. Detour maps for both the weekend closure and Stage 2 are available on the project website: www.seattle.gov/transportation/ppmp_mercer.htm.

The Washington Department of Transportation will be concurrently closing all SR 520 lanes and ramps from 11:00 p.m. Friday, January 13, to 5:00 a.m. Monday, January 16, between Montlake Boulevard in Seattle and Interstate 405 in Bellevue. SR 520 from I-5 to Montlake Boulevard will remain open to traffic. Details of the closure and detour maps are available at: www.wsdot.wa.gov/Projects/SR520Bridge/WeekendClosures.htm.

Mercer Street Stage 2 Traffic Switch Will Begin Following Weekend Closure

Following the weekend closure, Stage 2 of Mercer East will begin and eastbound traffic on Mercer Street will be re-routed onto the new Mercer Street lanes north of the existing lanes. Three lanes of traffic will continue eastbound on Mercer Street with access to the I-5 on-ramps and Fairview Avenue N.  Note that the southern-most lane of eastbound Mercer traffic will be required to turn southbound at Dexter Avenue in order to accommodate the lane conversion from four lanes to three.  This traffic shift will result in access restrictions to Mercer Street from the south, as access to Mercer Street via Boren, Terry, and Westlake Avenues will be concurrently closed at Republican Street.  Alternate routes should be used to reach Eastlake Avenue E and Capitol Hill (i.e. Dexter Avenue N to Republican Street).

Detour maps for the Stage 2 traffic switch for vehicles, bicyclists and pedestrians are attached and also available on the project website: www.seattle.gov/transportation/ppmp_mercer.htm.
