HARTFORD, Conn. — Republican state lawmakers, along with trucking and food-distribution executives, on April 28 declared war on Gov. Ned Lamont’s proposed regional climate initiative and user tax for heavy trucks on state highways.

A controversial bill on highway tolls was pulled from consideration on June 6, seconds before it would have been defeated on the House floor. It is likely to be dead for the year.

On its face, President-elect Donald J. Trump’s trillion-dollar plan for nationwide infrastructure improvements is good news, even for Democrats such as Connecticut Gov. Dannel P. Malloy.
