The ongoing Interstate 90 detours return again this weekend with another westbound closure, related to light rail preparations inside the Mount Baker and Mercer Island tunnels.

Starting at 11 p.m. on Friday, Feb. 10, the Washington State Department of Transportation will funnel westbound traffic from Bellevue to the center express lanes for construction purposes. The detour will end by 5 a.m. Monday, Feb. 13.

All westbound drivers wishing to exit onto Mercer Island must use East Mercer Way, but will have the option to continue through the interchange back onto the right lane of I-90, in order to exit at Island Crest Way.

As usual, there are no westbound exits from the express lanes.

Drivers wishing to reach Seattle from Mercer Island must enter the express lanes at Island Crest Way or 77th Avenue Southeast.

There are about a dozen more weekend directional closures of I-90 planned between now and mid-2017 while the state builds all-day bus and carpool lanes next to the regular lanes. This work will allow the center I-90 roadway to be dedicated to Sound Transit light rail construction in 2017.
