Neary $15 million will rebuild three miles of Route 12A over the next three years

A three-year, $14.8 million project on Route 12A that will impact traffic is starting later this month.

The New Hampshire Department of transportation plans to begin the project April 23 and it is set to end Aug. 28, 2020.

The three-year project will rebuild and widen three miles — from Main Street in North Walpole to NH 12A in Charlestown, Ron Guyette of DOT’s Construction Bureau said.

The project is to widen the roadway towards the Connecticut River, providing 11-foot lanes and four to five-foot wide shoulders on each side of the roadway, Guyette said.

“Right now there is no room on either side of the road to pull over,” he said.

The project is needed to add safety to the narrow highway, which has been eroding due to the Connecticut River that it runs alongside. The project includes reinforcing the slopes by using up to 80 feet of stones from the road down to the river creating an armored slope.

“This project here is going to armor the slope with upward of 80 feet of stone to prevent the road from sliding into the river,” he said.

The road project will also add drainage and storm water management, substantial utility relocation, and guardrail installation.

“Basically over the years the river has been eroding the bank along the roadway and it’s going to rebuild the road with added drainage to the road,” Guyette said.

Traffic impacts include mostly intermittent alternating one-way traffic. The project will have to work hand and hand with the rail line next to the road, he said.

“Motorists can expect delays due to lane shifts and construction equipment. Message boards and signs will be used to alert motorists of current conditions,” according to DOT.

Sargent Corporation of Stillwater, Maine, has been contracted for the $14.8 million project.
