The following is a release from the Washington State Department of Transportation:

All lanes of eastbound State Route 520 will be closed overnight Monday, May 4 between Montlake Boulevard and the highway on-ramp from Lake Washington Boulevard. The closure will last from 11 p.m. Monday to 5 a.m. Tuesday, May 5.

The eastbound ramp from Montlake Boulevard to the highway will also be closed. All other ramps will remain open, as will all westbound lanes of SR 520.

Crews working on the West Approach Bridge North Project will use the closure to cut a trench across the highway’s eastbound lanes in preparation for installation of a new sewer line.
