Here's another strange one: the "40 Connector" off I-91 to Route 10 in Mt. Carmel. Gotta be a good explanation for that one...
CT 40 Expressway, from CT 10 Expressway to I-95 in Branford
I often wondered why Mount Carmel needed a four-lane access from I-91. I never understood why this was there until I read about the proposed CT 10 Expressway.
Here's some photos of the "40 Connector" at its western termination at Route 10; photos facing northeast.
