WINDHAM, N.H. (AP) — New Hampshire Gov. Maggie Hassan is planning to sign a bill that raises the tax on gasoline and diesel by 4 cents per gallon, the first increase since 1991.
Hassan plans to sign the bill Tuesday at the new, not-yet-opened, southbound bridge at Exit 3 on Interstate 93 in Windham.
The tax increase would take effect July 1. New Hampshire's 18-cent tax is the lowest in New England and would remain the lowest with a 4-cent increase.
The bill increases funding for highway improvements for two years, then earmarks about half the proceeds to pay off $200 million in borrowing to finish the Interstate 93 expansion.
Once the debt is paid off in roughly 20 years, the tax increase would expire.
