New Hampshire officials are gathering public input on the state’s next 10-year transportation improvement plan, which outlines more than $4.5 billion in roadwork projects.

Residents of the Monadnock region will have three opportunities this month to weigh in on local projects included in the plan.

Executive councilor David Wheeler, whose district covers most of the Monadnock region, will host hearings at the Hillsborough Fire Station at 6 p.m. on Oct. 8 and at the Jaffrey Fire Station at 7 p.m. on Oct. 15. Executive councilor Karen Liot Hill will also hold a hearing at the Peterborough Town Library at 12 p.m. on Oct. 22.

Among the key projects open for comment is the long-delayed bridge replacement at Route 202 and Route 123 over the Contoocook River in Peterborough, with nearly $24.5 million budgeted for construction set to begin in 2028.

Overall, the Monadnock region is set to receive roughly $65 million over the next 10 years.

Many roadwork projects across the state are either partially or entirely nixed from the plan, Liot Hill said, and no new projects were accepted this year due to a $400 million shortfall in state and federal funds. The Monadnock area made it out relatively unscathed — no current projects were stripped.

State leaders are exploring a road toll and gas tax hike to ease the deficit.

Tolls in New Hampshire are the lowest cost per mile in the country, a state transportation official said at a previous hearing, and haven’t been raised since 2007. To increase them would require approval by the Executive Council.

The state’s gas tax — currently set at 23.83 cents per gallon of fuel — hasn’t risen since 2014.

“The cost of projects has only increased in that time and, in recent years, very significantly,” Liot Hill said. “The funds that were allocated are not … completing as much of the work as they were originally intended to do, and so that’s why we’re in the deficit and that’s why we’re interested to hear what people think about how to close that deficit.”

Liot Hill also said the state is on the hook for millions of dollars each year to pay loans it took out for transportation upgrades decades ago. That, combined with decades without fee increases and skyrocketing construction costs, has put the state government in the pinch it’s in now.

After soliciting feedback, the state Department of Transportation will submit the 10-year plan to the Legislature for approval next year. It’ll go into effect in 2027.
