Two highway ramps will be closed on Monday as crews work on the State Route 520/Montlake Project.

Beginning Friday night, the off-ramp to Lake Washington Boulevard closes from westbound SR 520, and the on-ramp to eastbound SR 520 closes from Montlake Boulevard.

Contractors are installing drainage along these ramps.

Westbound drivers can access Lake Washington by either exiting at Montlake Boulevard or the East Roanoke exit.

Drivers needing to head east across Lake Washington will have to access State Route 520 from I-5 in Seattle.

The exit to Montlake Boulevard remains open in the eastbound direction, and the bike trail will stay open.

During this project, the sidewalk remains closed on the west side of the Montlake Boulevard overpass, with a detour in place. The closure is expected to last until the end of January.

Ramps close Monday, Jan. 8 at 5 a.m.
