RVs are flatly banned on the Merritt and Wilbur Cross Parkways
Route 15 — the scenic Merritt Parkway, Wilbur Cross Parkway, and Milford Parkway — prohibits all RVs, campers, and trailers by law. CT DOT also caps any vehicle on these parkways at 8 ft tall, 24 ft long, and 7 ft 6 in wide. Your GPS will happily route you onto the Merritt to skip I-95 traffic; do not follow it in a motorhome. Use I-95 or I-91 instead.
