Drivers who use westbound State Route 520 (SR-520) through Redmond should plan ahead for lane and ramp closures from 10 p.m. tonight through 5 a.m. Monday.

Two right lanes of westbound SR-520 at Northeast 51st Street will be closed.

The westbound SR-520 off-ramp to Northeast 51st Street/Northeast 40th Street will be closed. A signed detour will be in place.

During the closures, contractor crews working for the Washington State Department of Transportation will move barriers and split the westbound SR 520 off-ramp to Northeast 51st and Northeast 40th streets into two separate exits. This work was originally scheduled for the weekend of Oct. 30 through Nov. 2 but was postponed due to wet weather.

Drivers will have access to the two separate off-ramps following the completion of lane and ramp closures this weekend. There will be one more weekend of closures in the coming weeks when the weather is appropriate for re-striping work. Crews will then return at a later date and complete work to install new lighting and overhead signs.
