Municipalities say the stalemate between Gov. Ned Lamont and legislators over long-term transportation funding is about to create an immediate crisis: With $30 million in promised local aid months overdue, fall tree trimming and winter snow removal are at risk. Lamont is delaying action on a bond package, saying he needs to know if lawmakers will provide new revenue for transportation or whether more of the state’s credit capacity will be needed to shore up the faltering special transportation fund. “‘This is more than just politics. It’s getting to be a public safety issue” said Joe DeLong, executive director of the Connecticut Conference of Municipalities.
