SR 520 Bridge, other highways to be closed during event-packed weekend

With summer almost coming to an end, the Washington State Department of Transportation is ramping up construction projects before our dry weather leaves the region.

The projects will cause parts of highways around Western Washington to close during a weekend packed with events.

The biggest closure of note is the State Route 520 Bridge, which will be shut down in both directions all weekend starting Friday night.

Here are some closures that are expected to cause congestion this weekend, followed by a list of large events.
