The 520 Bridge is completely closed this weekend, and this time the closure includes the trail.
Crews will close the bridge starting at 11 p.m. tonight (Dec. 1) and will reopen it 5 a.m. Monday (Dec. 4). The map shows that the trail will be open on the Eastside up to 92nd Ave NE.
The intense weekend of work includes pouring permanent pavement for the roadway deck as well as installing electrical and irrigation elements for the trail overpass in Montlake, which is why the trail must also be closed.
There are no easy detour options. Over the top of the lake, down to the I-90 Bridge or throw your bike on a bus, which will also be on a major reroute. So give yourself a lot of extra time if you need to cross the lake along the the 520 corridor. And if you’re traveling Sunday, check the 520 Construction Corner website in case they finish work early.
