I have lived in CT for 32 years, and been driving there for 22. In my unexpected and purely anecdotal survey conducted over the past two weeks, I think there's a problem with how some nav units are directing drivers of RVs. In all those years, I can count on half of one hand I've seen an over-height vehicle on there.
Both Sundays coming back from our lake house in the Quiet Corner, we encountered RVs around North Haven on the Wilbur Cross. First was a 5th wheel trailer type on the back of dually Super-Duty. This past weekend it was a ~12 foot tall Type C. Now, I don't excuse it entirely because you can't just blame following a computer's instructions blindly.
But please, if you are from outside the tri-state area and plan to visit or drive through in a taller vehicle, check your routes:
(lowest bridge for dramatic effect, but there are plenty in the 12 foot clearance range. that one is 10'-4").
