New Hampshire Gov. Maggie Hassan this week signed legislation increasing infrastructure funding by raising diesel and gasoline taxes in the state for the first time since 1991.

On July 1, both will increase by four cents per gallon, while remaining the least expensive in New England.

Revenues will help fund transportation improvement projects ranging from Interstate 93 to rural roads. Projects also include resurfacing and reconstruction on secondary roadways and municipal bridges.

“Our bipartisan transportation funding bill is the most significant state-level investment in transportation infrastructure in 23 years,” Gov. Hassan said. “This legislation is an important step toward addressing our transportation needs, keeping New Hampshire’s economy moving forward by advancing critical road and bridge projects, finishing the long-overdue expansion of I-93 and improving commutes for our workers and visitors.”

The legislation was supported by a bipartisan group of legislators from both legislative chambers and widespread support from the business community and other organizations, including the New Hampshire Business and Industry Association and various local chambers of commerce, among others.
