Connecticut needs to implement some form of electronic tolling on its highways. The state Department of Transportation has issued preliminary estimates that tolls could yield up to $800 million annually, providing a critical influx of funding to the State Transportation Fund. Continued dependence solely on the fuel tax will not get the job done. In 1997 the General Assembly cut the tax from 39 cents per gallon to 25 cents, leaving it unchanged since. The use of more fuel efficient cars and fully electric cars will continue to diminish the revenue raised through the gas tax.
