Heads up: Montlake Boulevard and several SR 520 ramps will close this weekend (Aug. 21-24)

If you use Montlake Boulevard or the SR 520 ramps in the Montlake area, plan for a weekend closure starting Friday night, Aug. 21.

From 10 p.m. Friday, Aug. 21, to 6 a.m. Monday, Aug. 24, Montlake Boulevard will close between East Hamlin Street and East Louisa Street, along with several nearby streets and SR 520 ramps.

So, what exactly is closing?

• Montlake Boulevard on-ramps to eastbound and westbound SR 520
• Eastbound SR 520 off-ramp to Montlake Boulevard
• A 300-foot section of East Roanoke Street west of Montlake Boulevard
• Lake Washington Boulevard between Montlake Boulevard and 24th Avenue East

The westbound SR 520 off-ramp to northbound Montlake Boulevard will remain open.

People walking, biking and rolling will still be able to cross SR 520 on Montlake Boulevard, with a limited detour south of SR 520.

What will crews be up to?

During the weekend closure, crews will install three new mast-arm sign structures and mount new signs on them. They’ll also remove the large sign bridge spanning Montlake Boulevard just south of SR 520 and install a new southbound sign north of SR 520 on an existing utility pole.

If you’re traveling through Montlake this weekend, give yourself extra time, check the real-time travel map and consider alternate routes.
