Drivers who use westbound State Route 520 through Redmond should plan ahead for lane and ramp closures from 6 a.m. to 4 p.m. on Saturday, Feb. 20.
- The right lane of westbound SR 520 from West Lake Sammamish Parkway Northeast to Northeast 40th Street will be closed.
- The westbound SR 520 off-ramps to Northeast 51st Street and 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 install new overhead signs and lightning. This work is the final phase of a project to split the westbound SR 520 off-ramp to Northeast 51st and Northeast 40th streets into two separate exits to reduce congestion in the area.
