A low water crossing (also known as an Irish bridge, causeway in Australia, low level crossing or low water bridge) provides a bridge when water flow is low. Under high flow conditions, water runs over the roadway and precludes vehicular traffic. This approach is cheaper than building a bridge to raise the level of the road above the highest flood stage of a river, particularly in developing countries or in semi-arid areas with rare high-volume rain.

Famous quotes containing the words water and/or crossing:
“The clock runs down
timeless and still.
The days and nights turn hours to years
and water in a gutter marks the circle of another world
hating, resentful, and afraid
stagnant, and green, and full of slimy things.”
—Margaret Abigail Walker (b. 1915)
“Bodhidharma sailing the Yangtze on a reed
Lenin in a sealed train through Germany
Hsuan Tsang, crossing the Pamirs
Joseph, Crazy Horse, living the last free
starving high-country winter of their tribes.
Surrender into freedom revolt into slavery—”
—Gary Snyder (b. 1930)
