Drivers heading south of Boston will run into some delays as a new construction project is leading to detours on Route 3 in Braintree.
The Route 3 bridge replacement project means detours and a lane closure in Braintree this weekend.
Starting Friday night at 10, a lane will be closed at Route 3 northbound near exit 19. Detours include Washington Street and the Burgin Parkway.
Officials with the Massachusetts Department of Transportation say the $6.3 million project, which will be accelerated, will involve replacing two Route 3 bridges that pass over an I-93 ramp just south of the Braintree split.
Transportation officials recommend avoiding the area if you can. People who know this area say they're expecting a congested area to be even worse during construction.
"I think now is a lot better time than the summer obviously. But traffic in Braintree historically is very congested," Tom Ryan, who grew up in Braintree, said.
"You can just get off and go through the back, Washington Street, 37. I think it'll just increase the traffic in Braintree," Braintree resident Steve Doyle said.
I-93 will remains open in both directions despite the detours and lane closure.
This weekend's work lasts through early Monday morning, while construction on the southbound section of the bridge is scheduled for the weekend of Oct. 13.
