MILFORD — Drivers traveling I-95 through New Haven, West Haven, Orange and Milford are dealing with two state highway jobs at once this week: overnight lane closures for catch-basin cleaning that are scheduled through Nov. 23, and a shift of all southbound traffic in West Haven onto newly built lanes on Wednesday and Thursday, Nov. 11 and 12.
Both schedules come from the Connecticut Department of Transportation. The work can move if the weather turns or other delays come up, CTDOT says, and drivers are asked to keep a safe speed in the work zones.
Overnight closures for catch-basin cleaning, through Nov. 23
In a revised construction advisory, CTDOT says crews will clean catch basins, also called scuppers, on bridges along I-95 northbound and southbound between Exits 51 and 33 in New Haven, West Haven, Orange and Milford. The project, DOT01730554CN, is being done by Mohawk Northeast Inc.
The work is scheduled from Sunday night, Nov. 8, through Monday, Nov. 23, with various lane closures from 7 p.m. to 5 a.m. State police, traffic-control signing and crash units are to guide motorists through the zone. The advisory says the cleaning is now planned in phases, and that CTDOT will release an updated schedule for later phases once the first phase is finished, weather permitting.
The start was originally set for Nov. 1 and was postponed to Nov. 8 because of contractor availability, the department said. News 12, in a Nov. 9 report, said the overnight closures would run from 7 p.m. to 5 a.m., Sunday through Thursday, and that CTDOT described the cleaning as work to reduce flooding on bridges along the highway.
Southbound traffic in West Haven moves this week
Separately, CTDOT says all I-95 southbound traffic in West Haven is scheduled to shift onto newly constructed southbound lanes during the days of Nov. 11 and 12, in preparation for the next stage of work. That project, No. 0156-0181, is the replacement of Bridge 00161, which carries I-95 over First Avenue, and Bridge 00162, which carries I-95 over Metro-North Railroad.
According to the department’s updated advisory, last revised Nov. 4, the project was awarded to The Middlesex Corporation with H&H, LLC, at a cost of $96,688,000 on Aug. 25, 2023, and is scheduled to be completed in November 2027. It is administered by CTDOT’s District 3 office in New Haven.
The Exit 43 on-ramp to I-95 northbound from First Avenue in West Haven remains closed until November 2027. CTDOT lists two detour routes for motorists trying to reach I-95 north: First Avenue southbound to Route 122 (Kimberly Avenue) and Ella T. Grasso Boulevard in New Haven, to Interchange 44; or Campbell Avenue northbound to Boston Post Road and Ella T. Grasso Boulevard, also to Interchange 44. Traffic-control signs are to mark the detours. A map is posted on the project site at i95westhaven.com/traffic-detour-information.
