According to the State Department of Transportation (MassDOT), at 7 p.m. crews will be arriving at the Needham-Dedham town line to work on splitting the traffic lanes.
"The traffic split is necessary to reconstruct a portion of the bridges that carry I-95 South over the Charles River. The bridges on I-95 North and South are being reconstructed and widened to accommodate a fourth travel lane as part of the “Add-A-Lane” project," the MassDOT said in a statement.
The Boston Globe is reporting that the work to split to lanes should last until noon on Saturday.
But while work is being done, Exit 18 and Exit 17 southbound will be closed and detours will be put in place.
"Once the split is complete, the exits will reopen, though they will only be accessible from the right lanes," the department told the Globe.
