LONDONDERRY — As the Interstate 93 work continues, the New Hampshire Department of Transportation announces a schedule of night traffic detours and lane closures.
NHDOT announces the night work on I-93 northbound and southbound continuing at Exit 4 in Londonderry.
This work consists of removing concrete abutments for the old New Hampshire Route 102 bridge over the interstate, and then, beginning on or about Nov. 15, the demolition of the old Ash Street bridge over I-93.
The work is scheduled to be done between the hours of 7:30 p.m. and 6 a.m. and will require the use of lane closures and detours.
Northbound traffic will be diverted nightly to the Exit 4 off-ramp and back on to I-93 until on or about Nov. 15, then lane closures will be used for the remaining northbound and southbound work.
The work is expected to continue until the end of November, but additional nights may be needed due to weather conditions. Message boards, traffic control devices and smart work zone devices will be used to help notify the traveling public.
The work is part of the state's final I-93 mainline construction in the Exit 4 area near Derry/Londonderry, as well as the Exit 4 on and off ramp reconstruction plan, the New Hampshire Route 102 reconstruction, including the rebuilding of the Route 102 bridge over the interstate, and Pillsbury Road/Ash Street, including the Pillsbury Road/Ash Street bridge over I-93.
The $62.2 million project is scheduled for completion in the fall of 2020.
