Hooksett Toll Plaza Open Road Tolling Conversion

New Hampshire


HNTB helps bring open road tolling to key New Hampshire toll plaza 


HNTB provided final design and construction support services to widen and retrofit the New Hampshire Department of Transportation’s Hooksett Toll Plaza, enabling open road tolling at this key toll plaza. 

The project converted six conventional toll lanes to four ORT lanes (two northbound and two southbound). The toll lanes are separated by concrete barrier from conventional toll lanes on each side of the plaza. 

Hooksett processes more than 25 million vehicles a year and up to 80,000 vehicles a day during summer months.
