A low-water crossing (also known as an Irish bridge or Irish Crossing, causeway in Australia, low-level crossing or low-water bridge) is a low-elevation roadway traversing over a waterbody that stays dry above the water when the flow is low, but is designed to get submerged under high-flow conditions such as floods.
Fords may be impassable during high water. A low-water crossing is a low bridge that allows crossing over a river or stream when water is low but may be treated as a ford when the river is high and water covers the crossing. The word ford is both a noun (describing the water crossing itself) and a verb (describing the act of crossing a ford).
A train was parked on the bridge to help hold it in place. The peak level was estimated to be about 13 metres (42 ft) above low water level. [4] Streetcars used the bridge (on a gauntlet track) from 1908 to 1939. [5]: 17, 116 Trolley buses of the Edmonton trolley bus system used the bridge from the removal of the streetcar track in 1939 until 1965.
However, the presence of the submerged bridge structure limits the draft of vessels in the waterway. The term submersible bridge is also sometimes applied to a non-movable bridge that is designed to withstand submersion and high currents when the water level rises. Such a bridge is more properly called a low water bridge.
Royal Gorge Bridge, highest bridge in the United States. This is a list of the highest bridges in the United States by height over land or water. Height in this list refers to the distance from the bridge deck to the lowest point on the land, or the water surface, directly below.

The reference water levels are used on inland waterways to define a range of water levels allowing the full use of the waterway for navigation. [1] Ship passage can be limited by the water levels that are too low, when the fairway might become too shallow for large ("target", "design") ships, or too high, when it might become impossible for the target ships to pass under the bridges.
