The New Hampshire Department of Transportation (NHDOT) announces traffic impacts for planned night work associated with the I-93 expansion between Exits 4 and 5 in Londonderry. Weather permitting, pavement marking work for a new traffic pattern will take place during nighttime hours from Monday, November 20th into Tuesday, November 21st. The work is scheduled to be done between the hours of 8:00 pm and 5:30 am and will require the use of lane closures to perform the work. Traffic on I-93 southbound between mile markers 12.6 and 15.8 will be reduced to one lane. Message boards and smart work zone devices will be used to notify the traveling public. Motorists should remain alert while traveling through the construction zone and obey all posted signs. This work is part of the $35 million I-93 widening and reconstruction project between Exit 4 in Derry and Exit 5 in Londonderry. The general contractor is Weaver Brothers Construction from Bow, NH.
