Full closure of I-5 on-ramps and off-ramps planned for August 24-27, 2012
Ramp closure hours will be from Friday at 11:00 p.m. to Monday at 5:00 a.m. on race weekend, August 24-27. Detour routes shown will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound.
Please plan your route accordingly and allow additional time to arrive at the course.
During these closures, the I-5 on-ramp at University St. will be concurrently closed to provide more efficient traffic flow around the closed Mercer St. exit lane. Fairview Ave. N will also be closed between Mercer St. and Valley St., and Mercer St. will be closed to through traffic between Westlake Ave. N and Fairview Ave. N. All detour routes will be clearly marked.
Beginning Thursday, August 23, a single lane on Mercer St. will be closed between Boren Ave. N and the Mercer St. I-5 on-ramps to accommodate median work near Fairview Ave. N that will facilitate the transition to two-way traffic on Mercer St. The closure will be in effect beginning Thursday, August 23, at 7:00 p.m. through Friday, August 24, at 11:00 p.m., when the full weekend ramp closure will commence.
