The Seattle Department of Transportation (SDOT) will be closing down the I-5 on and off ramps at Mercer Street again this weekend, as part of ongoing work needed as part of the Mercer Corridor Project.
The closure will begin at 11 p.m. on Friday, June 17, and go until 5 a.m. on Monday, June 20. Detour route maps are available here. From SDOT:
Detour routes shown will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound. Travelers are advised to consider alternate routes to their destinations such as SR 99 or alternate I-5 exits and entrances.
After this weekend’s closure, the Mercer Street access to and from I-5 will not be closed again until the weekend of July 8-11, and is scheduled to take place during the same hours. From SDOT:
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 also be closed between Mercer Street and Valley Street and Mercer Street will be closed to through traffic between Westlake Avenue N and Fairview Avenue N. All detour routes will be clearly marked to support traffic flow around the closures.
SDOT is advising travelers heading to the Fremont Solstice Parade and Fair to use SR 99 or to the alternate I-5 off-ramps at Olive Way (northbound) or Stewart St. (southbound) and Denny Way to Westlake Ave. N. More information on routes to the Fremont Fair can be found at the fair website.
Travelers are encouraged to carpool and use alternate modes of transportation. Transit information can be found at:
