RoadsThe Interstate highways in the state are I-95 (the Connecticut Turnpike) running southwest to northeast along the coast, I-84 running southwest to northeast in the center of the state, I-91 running north to south in the center of the state, and I-395 running north to south near the eastern border of the state. The other major highways in Connecticut are the Merritt Parkway and Wilbur Cross Parkway, which together form State Route 15, running from the Hutchinson River Parkway in New York State parallel to I-95 before turning north of New Haven and running parallel to I-91, finally becoming a surface road in Berlin, Connecticut. Route 15 and I-95 were originally toll roads; they relied on a system of toll plazas at which all traffic stopped and paid fixed tolls. A series of terrible crashes at these plazas eventually contributed to the decision to remove the tolls in 1988. Other major arteries in the state include U.S. Route 7 in the west running parallel to the NY border, State Route 8 farther east near the industrial city of Waterbury and running north-south along the Naugatuck River Valley nearly parallel with U.S. 7, and State Route 9 in the east. See List of State Routes in Connecticut for an overview of the state's highway system.
Between New Haven and the New York City, I-95 is one of the most congested highways in the United States. Many people now drive longer distances to work in the New York City area. This strains the three lanes of traffic capacity, resulting in lengthy rush hour delays. Frequently, the congestion spills over to clog the parallel Merritt Parkway. The state has encouraged traffic reduction schemes, including rail use and ride-sharing.
Connecticut also has a very active bicycling community, with one of the highest rates of bicycling ownership and use in the United States. New Haven's cycling community, organized in a local advocacy group called ElmCityCycling, is particularly active. According to the U.S. Census 2006 American Community Survey, New Haven has the highest percentage of commuters who bicycle to work of any major metropolitan center on the East Coast.
Public transportation
Rail
Southwestern Connecticut is served by MTA's Metro-North Railroad New Haven Line, providing commuter service to New York City and New Haven, with branches servicing New Canaan, Danbury, and Waterbury. Connecticut lies along Amtrak's Northeast Corridor which features frequent Northeast Regional and Acela Express service. Towns between New Haven and New London are also served by the Shore Line East commuter line. Operation of commuter trains from New Haven to Springfield on Amtrak's New Haven-Springfield Line is under consideration. Amtrak also operates a shuttle service between New Haven and Springfield, Massachusetts, servicing Hartford and other towns on the corridor.
Bus Statewide bus service is supplied by Connecticut Transit, owned by the Connecticut Department of Transportation, with smaller municipal authorities providing local service. Bus networks are an important part of the transportation system in Connecticut, especially in urban areas like Hartford, Stamford, Norwalk, Bridgeport and New Haven. A three-year construction project to build a busway from New Britain to Hartford will begin in August 2009.
