The trail on the 520 Bridge will remain open this weekend even as all lanes are closed to motor vehicle traffic. That motor vehicle closure is scheduled to extend from 11 p.m. Friday (today) until 5 a.m. Monday.
If you’ve never biked across the 520 Bridge when there is no car traffic, I highly recommend it. Stopping mid-span is so much more peaceful and quiet, the kind of mid-lake experience you can usually only get on a boat. So this weekend you can bike to Georgetown via the 1st Ave S temporary bike lanes, then head all the way up to a car-free 520 Bridge. Sounds like a pretty great set of weekend plans to me.
