The clearance below required under bridges for the largest ships—container ships, ocean liners and cruise ships—is around 220 feet (67 m) so there are often bridges with approximately that height located in coastal cities with bays or inlets, such as New York City's Verrazzano-Narrows Bridge and San Francisco's Golden Gate Bridge.

In waterways, "bridge span clearance" is a measurement from water surface to the underside of bridge span. The most conservative clearance uses the water level at the mean highest high water (MHHW), the average value of the highest high tide of a measurement period. This is known as "clearance below", "vertical clearance" and "charted height ...

Through urban areas, at least one routing is to have 16-foot (4.9 m) clearances, but others may have a lesser clearance of 14 feet (4.3 m). Sign supports and pedestrian overpasses must be at least 17 feet (5.2 m) above the road, except on urban routes with lesser clearance, where they should be at least 1 foot (30 cm) higher than other objects.
