The state transportation department would have the power to raise toll rates, starting in 2024, based on a working draft of a truck-only tolls bill that lawmakers plan to vote on next week. Estimates of how much the state would collect from truck-only tolls have ranged from $150 million to $200 million a year. The money would help fund a 10-year, $19.4 billion transportation plan. Tolls would only be paid by large tractor-trailer trucks, according to the draft. There would be no tolls, for example, for FedEx and UPS delivery trucks or oil trucks that deliver to homes. The highest prices would be charged on the Gold Star Memorial Bridge on the Groton-New London border and the Charter Oak Bridge off I-91 in Hartford. The base rate would be $12.80 for trucks with a Connecticut-issued E-ZPass. Those without a transponder would pay 50% more.
