    Prior to the study conducted by the USCG and the NYSDOT, options to ameliorate the issue included a new rail tunnel under the Hudson River, the rehabilitation of the Poughkeepsie Bridge, the use of the North River Tunnels, a cross-harbor rail ferry, the use of low-profile piggyback equipment and the use of the Harlem, New Haven, and Hudson Divisions through the removal of clearance restrictions.

    en.wikipedia.org/wiki/Clearance_(civil_engineering)

    In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a lock or diameter of a tunnel in the case of watercraft.

    The vertical clearance is 8 ft 11 in (2.72 m). The IRT Lexington Avenue Line of the New York City Subway , carrying the 4 , 5 , 6 , and <6> trains, runs parallel to the Park Avenue Tunnel in two tunnels below it.

    Alexander Hamilton Bridge in May 2024. The total length of the bridge, including approaches, is 2,375 feet (724 m). Its parallel main spans are 555 feet (169 m) long and provide 103 feet (31 m) of vertical clearance over the Harlem River at the center and 366 feet (112 m) of horizontal clearance.

    The bridge provided 35 ft (11 m) of vertical clearance, a channel width of 131 ft (40 m), and carried two 34-foot (10 m) three-lane roadways in either direction between 6-foot (1.8 m) pedestrian sidewalks. [11] After the bridge's first full year of operation, it had recorded at least 3,100 openings (roughly 8–9 times per day).

    Even though the original bridge was replaced in the 2000s, the new bridge also has a draw span, albeit with more vertical clearance resulting in fewer openings than the old bridge—about 65 per year, an average of about one every six days. I-695 has a drawbridge over Curtis Creek, south of Baltimore and just west of the Francis Scott Key ...

    The code also defines the clearance that is shorter than the physical clearance to account for sag curves, bridge deflection and expected settlements with a recommendation of minimum clearance of 5 metres (16 ft 5 in). [2] In UK, the "standard minimum clearance" for structures over public highways is 16 feet 6 inches (5.03 m). [3]
