Work continues on the Interstate 93 expansion project between Exits 4 and 5 in Londonderry with some traffic impacts planned this week as night projects gets underway.
The New Hampshire Department of Transportation announced the traffic impacts Monday as work continues on the $35 million I-93 widening and reconstruction project between those two exits.
Crews will be out doing night work, weather permitting, on drainage installation through Wednesday, Aug. 16.
The work is scheduled to be done between 9 p.m. and 5:30 a.m. each night. Traffic on I-93 northbound between mile markers 12.6 and 14.0 will be reduced to one lane.
There will be message boards and "smart work zone" devices used to notify travelers of the night work. Motorists should be alert while moving through construction zones and obey all posted signs.
The widening of a 20-mile segment of I-93 between Exits 1 and 5 — from the Massachusetts state line to the Interstate 293 split in Manchester — is one of the largest projects the DOT has ever undertaken, according to project manager Wendy Johnson who gave an update on the project to Londonderry town councilors last month.
The project passes through parts of Salem, Windham, Derry and Londonderry with phases broken down into specific work timelines.
Funding comes from the proceeds of a statewide gas tax and also from other federal funding sources, Johnson said.
The work close to Londonderry also plans to reconstruct areas near Kendall Pond Road to a southern portion near Exit 5, and also provide improvements to the on-ramp at Exit 4.
The I-93 project also includes the repair of more than 40 of the state's worst bridges, Johnson noted. There are 19 “red-listed” bridges that are being removed as part of the overall I-93 project.
