Drivers should plan ahead for nightly closures of the northbound and southbound Interstate 405 off-ramps to westbound State Route 522, Tuesday, March 3 through Thursday, March 5.

Crews will close the southbound Interstate 405 off-ramp at 9 p.m., and the northbound Interstate 405 off-ramp at 11 p.m. each night.

Both ramps will re-open by 5 a.m. the following morning.

Drivers will follow a signed detour using the Beardslee Boulevard exit to State Route 522.

During the closures, crews will install a 70-foot-long detention vault to capture roadway runoff from State Route 522 near the southbound Interstate 405 ramp.

This work is part of the State Route 522 UW Bothell/Cascadia Community College Access Project.
