1. There isn’t enough money. Connecticut’s special transportation fund is on a path to insolvency, with gasoline tax revenues flat because of more fuel-efficient vehicles and electric cars. Transportation officials say that annual maintenance alone costs $1.2 billion. So if the state is going to embark on billions of dollars of transportation projects, it will need a consistent revenue stream. The punch list of projects includes the I-84 viaduct overhaul in Hartford, the replacement of the Waterbury “mixmaster,” the junctions of I-84 and Route 8, I-95 congestion mitigation near Bridgeport and the widening of I-84 in Danbury.
