The Seattle Department of Transportation (SDOT) reminds travelers of the full weekend closure of the I-5 on- and off-ramps at Mercer Street and accompanying street restrictions on Fairview Avenue N and Mercer Street this weekend as part of the Mercer Corridor Project.
The full closure of the I-5 on- and off-ramps at Mercer Street is scheduled for this weekend, May 3 – 6 from Friday at 11:00 p.m. to Monday at 5:00 a.m. During the closure, crews will be installing sign bridges across the I-5 on- and off-ramps at Mercer Street, performing base repair on the on-ramp, installing final asphalt paving on the on-ramp, and rechannelizing the intersection of Mercer Street and Fairview Avenue N. Note that this work is dependent on weather and is subject to cancelation.
Detour route maps are available at: www.seattle.gov/Transportation/mercercorridor.htm. Detour routes shown will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound. Please note that all South Lake Union businesses will remain open and will be accessible via alternative routes.
During these closures, the I-5 on-ramp at University Street will be concurrently closed to provide more efficient traffic flow around the closed Mercer Street exit lane. Fairview Avenue N will be restricted to freight, King County Metro transit, and local access only between Republican Street and Eastlake Avenue E. Mercer Street will be closed to through traffic between Westlake Avenue N and Fairview Avenue N. All detour routes will be marked.
Travelers are encouraged to carpool and use alternate modes of transportation. Transit information can be found at:
