The state of Connecticut does not have toll roads, making it the only state along the East Coast without any tolls. Tolls were abolished in Connecticut in 1983 due to federal legislation that blocked states with highway tolls from using federal funding for road projects.
Of course, since they were scrapped, there has been plenty of debate in Connecticut about whether tolls should be reinstated, as they generated millions of dollars in revenue for the state. However, according to the state government, there would be a steep cost to reinstating those tolls—Connecticut would have to pay back roughly $3 billion in federal funds received once tolls were abolished.
