Crews working for the Washington State Department of Transportation will close a major off-ramp in Redmond this weekend to install drainage under the roadway. This work is part of a project to widen SR 520 by adding a new HOV lane and a merge lane in each direction between West Lake Sammamish Parkway and SR 202.

• 8 p.m., Friday, April 16–5 p.m., Saturday, April 17: Crews will completely close the ramp from westbound SR 520 to West Lake Sammamish Parkway to install drainage. A detour will direct drivers to the NE 51st Street ramp, back onto eastbound SR 520 to West Lake Sammamish Parkway.
