DERRY — The widening of Interstate 93 between Windham and and Londonderry is on schedule, according to a recent update from the New Hampshire Department of Transportation

Efforts to widen the north and southbound lanes in that 3 1/2-mile stretch are 65 percent complete. The $54 million leg of the project is on track for an October 2018 completion, according to I-93 corridor supervisor Jay Levine. 

This is part of the state’s $800 million project to widen a 20-mile stretch of I-93 between Salem and Manchester. 

The DOT is preparing for winter by cleaning up roadways and changing traffic patterns a last time before the year ends.

“At night they’re doing a little paving to take care of some blasting damage,” Levine explained. “It’s a house-cleaning effort to set us up for the winter months. As you progress south, between Exits 4 and 5, they’re going to be working later in the week to shift traffic to a newly constructed portion of roadway.”

Similar work was done on the opposite side of the highway last month, before Thanksgiving.

“I don’t think this will do anything for mitigation of congestion, but it will definitely be a better riding surface,” Levine said. “Drivers aren’t going to see much change in traffic through the corridor until the later part of next year. At that time they might see some opening up on I-93 south below Exit 4.”

Drivers should be aware of this shift in traffic flow and nighttime work. As always, they should pay particular attention to their speed and all posted signs in construction zones, DOT officials said.

Levine said during several nights next week there will lane closures again while workers hang structural steel for the Route 102 Bridge at Exit 4. This work is scheduled to be done between 7 p.m. and 6 a.m.

Northbound and southbound traffic will be diverted nightly to the Exit 4 off-ramps and back onto I-93. Message boards, uniformed officers, traffic control devices, and smart work zone devices will be used to notify the travelling public. This work is expected to take three weeks to complete, however, additional nights may be required due to weather conditions, officials said.

“Work in the rest of the corridor will be somewhat quiet,” Levine said. “The rest of it is going into shutdown for the winter months.”

At the end of what the project manager called another successful season of work, the DOT on Nov. 6 also opened a new 140-space park and ride off of Exit 3 in Windham.

The $2.1 million project took a year to complete. It features a bus shelter, though there are currently no bus services, as well as a concrete pad for motorcycles and a bicycle rack.
