Spring is here and with it, very soon, the sounds of heavy lifting for the $800 million Interstate 93 widening project in Southern New Hampshire.
This construction season has about $162 million in projects from Exit 5 in Londonderry through Exit 1 in Salem to the Massachusetts line.
“You’re going to see changes constantly out there,” said Jay Levine, New Hampshire Department of Transportation I-93 coordinating supervisor.
Weather will determine project startups, but Levine said the construction action will be moving ahead during April and May.
Snowmelt and runoff are a consideration for the moment.
Crews already are on the job. DOT’s Jon Bradstreet, a contract administrator, said activity is visible at Exit 3 in Windham.
“People should currently see some activity, but it shouldn’t impact them too much,” Bradstreet said, “just trucks coming in and out.”
There are four major projects between Exits 1 and 5 that will affect motorists this construction season.
Middlesex Corp. of Littleton, Mass., has a $32.7 million highway widening and bridge project at Exit 1 in Salem slated for completion this year.
George R. Cairns & Sons of Windham has a $43.6 million project at Exit 2 in Salem involving interchange reconstruction, bridge and ramp work. Work will continue into 2015.
R.S. Audley Inc. of Bow has a $35.1 million southbound widening project at Exit 3 in Windham that also involves relocation of a section of Route 111. Work is expected to be done in 2016.
Severino Trucking Inc. of Candia has the $37.3 million Exit 5 interchange and Route 28 improvements in Londonderry. Work is expected to wrap up next year.
In addition to those major projects, E.D. Swett Inc. of Bow has a $12.1 million bridge replacement project at Exit 3. That is due to be completed this year.
When all expenses such as transit subsidies are included, the $800 million highway widening is the most costly in state history.
