Here's what to expect if you're traveling this Labor Day weekend

Increased traffic congestion due to Labor Day weekend travel is expected to start early Friday afternoon.

The Massachusetts Department of Transportation advised drivers in Greater Boston to consult mobile navigation apps like Google Maps, Apple Maps and Waze before hitting the road.

State Highway Administrator Jonathan Gulliver said the agency updates those apps with real-time traffic conditions, which can help drivers avoid traffic jams over the holiday weekend.

"Even if you make a commute every single day and you know your route, use that tool, because it's gonna re-route you around some of the heaviest congestion," Gulliver said. "It's a way to get you to your destination in the most efficient and safe way possible."

For travelers flying out for the weekend, Aviation Director Ed Freni said traffic to and from Logan International Airport should be manageable, because Sumner Tunnel remains open this weekend.

Scheduled construction projects shifted to account for increased travel. However, Freni said weather conditions in other parts of the country may still impact flight delays and cancellations.

"We are doing our best as an airport operator to facilitate the airline schedules," he said. "Hopefully Mother Nature will be kind to us, and we'll have a pretty smooth transition for people."

Boston-area weather promises to be pleasant for travelers on Saturday, according to meteorologist Danielle Noyes. However, she said the forecast shows Sunday and Monday could bring chances of scattered thunderstorms or showers worth watching out for, especially if you're heading to and from outdoor events.
