Note: The national AASHTO 1994 "Policy on Geometric Design of Highways and Streets", a non-binding guide on the states, recommends a minimum vertical clearance for new bridges of 14' 5" but RECOMMENDS 16' 5"As desirable. Conn DOT AIMS FOR 16' 7" CLEARANCE FOR NEW BRIDGES, BUT sometimes permits new STRUCTURES at 13' 9" on state roads to allow ONLY the legal truck height to pass. Connecticut State Statute 14-264 sets a height limit of 13' 6" for vehicles operating on state roads, unless a waiver is obtained from Conn DOT.
