Most statewide construction projects are taking a break this Labor Day weekend, but drivers heading into Seattle might be working overtime behind the wheel to get to their destinations due to several events that will create heavy traffic.

The Washington State Department of Transportation urges drivers to add extra time to their trips and plan ahead for increased congestion on Interstate 5. Seattle traffic is anticipated to be heaviest on Saturday, Sept. 1, with volumes building by 10 a.m., continuing into the afternoon and then tapering off in the evening hours.
