The state Department of Transportation released a preliminary report Friday, shedding new light on how much revenue tolls could bring to Connecticut.

New findings predict that an estimated $1 billion per year could be raised for the state if tolls are installed. The agency has considered the majority of the state’s major highways as part of their study, including Routes 15, 9,  and 2.

According to the preliminary report, a total of 82 gantries would be added to the state’s roadways

One of the many objectives of the initial study was to determine just how much revenue could be gained to help pay for transportation infrastructure improvements in the state.

A recent report from the Connecticut Society of Civil Engineers gives the state a C minus for an overall infrastructure grade.

According to the newly released information, tolls could raise “substantial revenue with low rates” for residents of Connecticut. Residents would be given a discount if they held a state-issued E-Z pass, and a commuter discount if they use the highways frequently. 

Out-of-state drivers would pay more if they don’t have a Connecticut-issued E-Z pass. The report also estimates that approximately 40 percent of the toll revenue would come from out-of-state vehicles.

The DOT says charging higher rates during peak traffic times and lower rates in off-peak would help to reduce congestion during normal peak periods. 

Officials warn that this report is in advance of a more in-depth analysis that the State Bond Commission approved $10 million for back in July. The controversial approval faced much opposition from the state’s House republicans.
