All westbound lanes of SR 520 between Montlake Boulevard and I-5 in Seattle are scheduled to close at 11 p.m. Friday and reopen by 5 a.m. Monday.

Drivers will still be able to cross Lake Washington during the closure, but westbound traffic will have to exit at Montlake Boulevard or Lake Washington Boulevard instead of continuing toward I-5.

Eastbound SR 520 will remain open, and the SR 520 Trail will stay open as well.

The closure is planned so crews can repair expansion joints on westbound SR 520 and shift the westbound off-ramp to northbound I-5 farther north as part of the SR 520 Portage Bay and Roanoke Lid Project.

The timing overlaps with a busy weekend in Seattle, including Garth Brooks at Climate Pledge Arena, the Seattle International Auto Show, and other events around Seattle Center, which could add to traffic for people coming from the Eastside.

The closure is weather-dependent, and drivers headed toward I-5 will need to use alternate routes.
