Drivers heading through New Haven will have to find a different route if they're headed over Grand Avenue.
The road will be closed for a month, according to city officials.
It closed at 7 a.m. on Monday between James and East Streets.
The shutdown is to overhaul and upgrade the Providence and Wooster railroad crossing of Grand Avenue. Money for the work came from a federal grant.
Officials called a major four-week undertaking.
"A week from Thursday, these tracks will come out," said Pete Lozis, City of New Haven. "Utilities will be able to go under the tracks and on Saturday morning, the tracks will be put back in service."
Officials said people will be able to walk through the construction zone. Bicyclists will also be able to get through it; however, they'll likely be asked to walk their bikes across.
All traffic will be detoured through Chapel Street.
