Do you have plans for Labor Day? Plan ahead for holiday travel, and make sure this summer goes down in the books as a safe one.

The Virginia Department of Transportation (VDOT) will suspend most highway work zones and lift most lane closures on interstates and other major roads in Virginia from noon Friday, Aug. 31, until noon Tuesday, Sept. 4.

While lane closures will be lifted in most areas, motorists may encounter semi-permanent work zones that remain in place during this time. A full listing of those lane closures can be found on VDOT’s website.

VDOT’s online, interactive travel-trends map shows peak congestion periods on Virginia interstates during previous Labor Day holidays. While it can’t precisely predict when congestion will occur this year, it can help you plan travel around those times when roads have historically been busiest.

Based on the traffic data, periods of moderate to heavy congestion are most likely to occur between noon and 6 p.m. on Friday and Monday.

VDOT’s 511 app offers information about construction, traffic, incidents and congestion as well as access to traffic cameras, weather and more. The free mobile VDOT 511 app is available online. Traffic information is also available at 511Virginia.org, or by calling 511 from any phone.

To report a road problem or get answers to your transportation questions, call VDOT’s Customer Service Center at 800-FOR-ROAD (800-367-7623).
