---- — CONCORD — A New Hampshire firm will get a $32.2 million contract to widen a section of Interstate 93 in Salem and Windham.
The governor and Executive Council this week approved the deal with Weaver Brothers Construction Co. Inc. of Bow.
The company was the low bidder.
Transportation Commissioner Christopher Clement, in a memo to the governor and council, reported the contract came in $3.6 million under estimate.
“This project involves the construction of 2.2 miles of I-93 mainline and another 2.75 miles of pavement, final overlay work, beginning near the Exit 2 northbound on ramp and transitioning to the existing northbound layout, north of Exit 3 near the weight station facility,” Clement wrote.
“This project also completes the relocation of N.H. 111, N.H. 111A, and the northbound half of the Exit 3 interchange,” Clement said.
The project will represent a milestone for Windham.
“This is the fifth and final project required to complete improvements at Exit 3,” Clement told the governor and council.
Final completion is expected by October 2016.
A Transportation Department analysis said two travel lanes north will be maintained at all times.
Rolling roadblocks will be allowed during non-peak commuter hours for some construction operations.
“The existing northbound ramps, N.H. 111 and N.H. 111A traffic will be affected during construction due to the tie-in locations and the construction of minor traffic diversions necessary to maintain traffic,” the analysis said.
“Alternating one-way traffic will be allowed on Range Road (existing NH 111A), and West Shore Road,” it said.
There will be flaggers and uniformed officers used as necessary.
