Gov. Ned Lamont’s push to get the General Assembly’s approval for tolls began last January, but has failed to be called for a vote since then. When the legislative session ended last spring, the administration aimed to generate support over the summer and bring it across the finish line during the fall, after municipal elections. That goal has been pushed back month after month, and the administration is now aiming for a vote before the legislative session begins Feb. 5. But that window is closing. No vote is scheduled this week and legislators have not been told to reserve a date to come in for a vote. Lamont said his staff is working with legislative leaders to get a vote scheduled.
