The Seattle Department of Transportation (SDOT) reminds the public of two upcoming weekend closures of the I-5 on- and off-ramps at Mercer Street. Full weekend closures as part of the Mercer Corridor Project will occur the following weekends in July:
• July 8 – July 11
• July 22 – July 25
Closure hours are anticipated to be Fridays at 11:00 p.m. to Mondays at 5:00 a.m.
Detour route maps are available on the project website at:
www.seattle.gov/Transportation/ppmp_mercer.htm. 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.
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.
The Washington State Department of Transportation will be concurrently closing all lanes on SR 520 from 11:00 p.m. Friday, July 8, to 5:00 a.m. Monday, July 11, 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.
