Interstate 91 (abbreviated I-91) is a north–south Interstate Highway in the state of Connecticut. The interstate's southern end is in New Haven, Connecticut at Interstate 95.

Route description[edit]

I-91 has an HOV Lane between Hartford and Windsor

Interstate 91 is the major north–south transportation corridor for the center of the state. It is the main route between the larger cities of New Haven, Hartford, and Springfield, Massachusetts. As such, it is almost always heavily trafficked (especially during rush hour), and maintains at least three lanes in each direction through Connecticut except for a short portion in Hartford at the interchange with Interstate 84. The three cities also serve as Connecticut's control points along its length of the Interstate. Overhead signs in each direction consistently feature one or two of the cities, although very few (if any) conventional highway mileage signs are placed along the Interstate in Connecticut that indicate the remaining distance between the cities.

The highway begins just east of downtown New Haven at the intersection with the Connecticut Turnpike Interstate 95 and Connecticut Route 34 at the Pearl Harbor Memorial Bridge, or Q Bridge as referred to by the locals. At the bottom of the ramp for Exit 5, U.S. Route 5 has its southern terminus and the first of its many interchanges with the freeway. Leaving New Haven, I-91 follows a northeastward trek through New Haven's suburbs of North Haven and Wallingford before entering the city of Meriden. In Meriden, about halfway between Hartford and New Haven, I-91 sees an interchange with its first spur route, Interstate 691. I-691 provides a westward link to Interstate 84 and the city of Waterbury. Leaving Meriden, I-91 travels briefly through Middletown before passing through Cromwell, Rocky Hill, and Wethersfield, eventually entering the Hartford city limits. Just south of Hartford, the highway begins to directly parallel the Connecticut River. In Hartford, I-91 interchanges with I-84 before leaving the city limits. I-91 will maintain an urban character throughout its distance to Springfield. Halfway between the two cities, Exit 40 provides direct access (via Connecticut Route 20) to the Bradley International Airport. I-91 runs through Windsor, Windsor Locks, East Windsor and Enfield (with several exits in each town) before crossing into Massachusetts at milepost 58.

I-91's final exit in Connecticut is Exit 49, which offers northbound travelers access to Longmeadow, Massachusetts, after which I-91 enters Massachusetts.

History[edit]

In the 1970s there were plans to extend I-91 across the Long Island Sound from New Haven, Connecticut to Long Island in New York. The extension would continue south to the southern shore of the island perhaps along the route of the current William Floyd Parkway[citation needed] in central Suffolk County. It would also provide easier access to New York City via the Long Island Expressway, as well as to The Hamptons via Sunrise Highway (New York State Route 27).
