Alert 4/28-5/1: 520 Trail closed across Lake Washington

Map of the closed trail sections, from WSDOT.

The 520 Bridge Trail will be closed late Thursday through late Sunday, WSDOT announced Wednesday. The trail under the bridge leading to Lake Washington Boulevard will also be closed.

A previously-scheduled closure was cancelled earlier this month. You can check the 520 project's construction map to keep track of planned closures as details may change due to weather or other factors.

The trail closure is a major disruption for people who rely on this bridge, as all detour options add a lot of time and effort. For example, a bike trip from UW campus to downtown Kirkland takes about 45 minutes via the 520 Bridge, but 1:40 if traveling around the north side of the lake (according to Google's bike travel estimates). Remember that you can put most bikes on the front of a bus.

Details from WSDOT:

To keep riders and pedestrians safe as we pave and move soil nearby, we will close the trail across Lake Washington and the temporary trail under SR 520 from 3 a.m. Thursday, April 28 to 10 p.m. Sunday, May 1 at 10 p.m. Pedestrians and bicyclists should plan to take alternate routes across Lake Washington.
