Extended closure hours for March 29 and 30

Publish Date
Body

On Thursday, March 29 and Friday March 30, the Island Crest Way Westbound HOV on-ramp closure is planned to extend from 9 a.m. until 7 p.m. During this time, crews will pour a new concrete barrier on the north side of the station. A technique called "slip forming" where concrete is poured continuously into a moving form, will be used and the extended hours are needed to allow the concrete to set properly. Note: this work is weather dependent and may extend into Friday, March 30 if needed and drivers should follow signage.

Off-peak (9 a.m. – 3 p.m.) closures will resume at 9 a.m. on Monday, April 2. Drivers can use the West Mercer Way and 76th Avenue Southeast westbound on-ramps during this closure.
