The New Hampshire toll increase is happening. Lawmakers overrode Governor Kelly Ayotte’s veto of a major transportation bill, clearing the way for higher rates beginning January 1.

At the Hampton toll plaza, the standard passenger vehicle rate doubles from $2 to $4 on January 1, 2027.

What the Bill Does

The legislation forms part of the state’s 10-year transportation plan and provides additional funding for turnpike projects.

Supporters framed it as a response to a basic arithmetic problem: revenue has flattened while costs have not.

Senator Mark McConkey, vice chairman of the Senate Transportation Committee, said toll revenue has remained flat while the price of transportation projects keeps climbing. The additional money, he argued, will keep projects and other improvements moving.

The Out-of-State Argument

The central political case for the increase rests on who pays it.

McConkey described a preference he says residents expressed clearly: if improvements could be funded by drivers from Connecticut, Maine and Massachusetts passing through the state, while fees for residents stayed capped, that would benefit everyone.

New Hampshire’s geography makes that argument plausible. Interstate traffic moving between Massachusetts and Maine crosses the state, and those drivers use roads they do not fund through New Hampshire taxes.

The E-ZPass Distinction

The details of who actually pays more matter enormously here, and they are easy to miss.

According to a Department of Transportation spokesperson, vehicles listed on a funded New Hampshire E-ZPass account will continue receiving the NH E-ZPass rate, which matches today’s discounted rate.

Everyone else pays the new higher amount. That includes:

• Drivers paying cash
• Vehicles not listed on a funded New Hampshire E-ZPass account
• Out-of-state transponder holders

So the structure is designed to insulate residents who have set up and funded the state’s own transponder system, while raising costs for everyone else.

The Governor’s Objection

Ayotte vetoed the bill last month and did not soften her language.

She called it a tax increase on Granite Staters, pointing out that anyone paying cash will pay double, as will anyone who moved to the state without obtaining a new transponder.

She said she will always use her veto pen when it means stopping tax hikes, arguing that politicians will always want to spend more money, and that doubling costs makes life less affordable and crushes working families.

Her broader position centered on affordability and keeping New Hampshire attractive to tourists.

The Gap Between the Two Positions

Both sides are describing the same policy accurately while emphasizing different groups.

Supporters focus on residents who have E-ZPass accounts and will see no change. Ayotte focuses on residents who do not, including newer arrivals who have not set up transponders and anyone who still pays cash.

Neither characterization is wrong. The disagreement is about how many people fall into each category and how much the state should worry about them.

McConkey acknowledged the governor’s concerns but said he does not expect the increase to meaningfully affect tourism.

What Drivers Should Do

For anyone who regularly uses New Hampshire toll roads, one action prevents the increase entirely.

Obtaining and funding a New Hampshire E-ZPass account preserves the current discounted rate. Residents who moved to the state and kept a transponder from elsewhere will not receive the New Hampshire rate.

That distinction is worth checking before January.

The Broader Funding Problem

New Hampshire’s situation reflects a challenge facing transportation departments nationwide.

Construction costs have risen sharply in recent years while revenue sources tied to fixed rates have not adjusted. Fuel taxes have declined in real value as vehicles became more efficient and electric vehicles entered the fleet.

Tolls offer one of the few mechanisms that scales with usage and captures revenue from non-residents, which explains why states keep returning to them.

The tradeoff is that tolls are highly visible. Drivers see the amount every time they pass through a plaza, which makes increases politically difficult in a way that less noticeable revenue sources are not.

What Happens Next

The override settles the legislative question. Rates change January 1.

Whether the New Hampshire toll increase affects tourism, drives more residents to obtain transponders, or generates the revenue lawmakers projected will become clearer over the following year.

For now, drivers have several months to sort out their E-ZPass situation before the higher rate takes effect.
