Transportation in New Hampshire

Transportation in New Hampshire is characterized by a network of interstate highways, state roads, and limited public transit that serves its diverse geography from the Seacoast to the White Mountains. The state's New Hampshire Department of Transportation oversees a system that includes major routes like Interstate 93 and the Everett Turnpike, connecting key population centers such as Manchester, Nashua, and Concord. While heavily reliant on automobiles, the state also maintains regional bus services, a historic rail network, several commercial and general aviation airports, and active ports on the Piscataqua River.

Highways and roads

The backbone of New Hampshire's transportation network is its system of limited-access highways, most notably Interstate 93, which runs from the Massachusetts border near Salem through Manchester and Concord to Franconia Notch in the White Mountains. Other critical routes include Interstate 95, which skirts the Seacoast and connects to Portsmouth and the Maine border, and the Everett Turnpike, a vital commuter corridor serving Nashua and Merrimack. The New Hampshire Department of Transportation maintains an extensive network of state-numbered routes, such as Route 101, a major east-west artery linking Keene to the Seacoast, and Route 16, a key route through the Lakes Region and toward Berlin and the White Mountain National Forest. Notable bridges include the Memorial Bridge connecting Portsmouth to Kittery, Maine, and the Sarah Mildred Long Bridge, both spanning the Piscataqua River.

Public transportation

Public transportation in New Hampshire is primarily provided by regional bus agencies, with the largest being the Manchester Transit Authority, which serves the Manchester area, and Cooperative Alliance for Seacoast Transportation (COAST), which operates routes in the Seacoast including Dover, Portsmouth, and Rochester. The Nashua Transit System provides local service in Nashua, while intercity bus connections are offered by carriers like Concord Coach Lines, with hubs in Concord and Manchester providing service to Boston, Logan International Airport, and other New England destinations. The state also supports specialized services such as Advanced Transit in the Upper Valley region near Hanover and Lebanon, and Tri-County Community Action Program programs for rural areas.

Rail transportation

Freight rail operations in New Hampshire are dominated by Pan Am Railways, which operates former Boston and Maine Railroad lines, including a main line running from the Massachusetts border at Ayer through Nashua, Manchester, and Concord to Whitefield. Other significant freight carriers include the New England Central Railroad in the western part of the state and the St. Lawrence and Atlantic Railroad in the north near Berlin. Passenger rail service is limited to the Amtrak Downeaster, which makes stops in Exeter, Durham, and Dover on its route between Boston and Brunswick, Maine. Historically, the state was crisscrossed by lines of the Boston and Maine Railroad and the Concord and Montreal Railroad, with notable stations like the Concord station and the Portsmouth station.

Air transportation

The state's primary commercial airport is Manchester–Boston Regional Airport in Manchester, which offers scheduled passenger service by carriers such as American Airlines, Delta Air Lines, and United Airlines to major hubs. Other significant airports include Portsmouth International Airport at Pease at the former Pease Air Force Base, which handles cargo, corporate, and general aviation, and Lebanon Municipal Airport, serving the Upper Valley region. General aviation is well-supported by facilities like Boire Field in Nashua, Concord Municipal Airport, and Laconia Municipal Airport. The state also has several seaplane bases, particularly in the Lakes Region around Lake Winnipesaukee, and is within the service area of Boston Logan International Airport for international travel.

Water transportation

Maritime transportation is centered on the Piscataqua River, which forms a deep-water harbor shared with Maine. The Port of Portsmouth is a key facility, managed by the New Hampshire Division of Ports and Harbors, and includes the Market Street Marine Terminal and the Portsmouth Naval Shipyard on Seavey Island. The Port of New Hampshire handles various bulk and break-bulk cargoes. Inland, recreational boating is significant on major lakes like Lake Winnipesaukee, Lake Sunapee, and the Connecticut River, which forms the western border with Vermont. The state maintains public boat launches and marinas, and historically, canals like the Middlesex Canal and the Suncook River played roles in early industrial transport. Ferry service is limited but includes the seasonal Isles of Shoals Steamship Company from Portsmouth to the Isles of Shoals.
