A culvert is a structure that channels water past an obstacle or to a subterranean waterway.
A pipe laser, or another vertical distance measuring device is most commonly used for this. Invert levels are important for the drainage of a non-pressured fluid pipe. Typically, a good design requires that the invert level of the pipe will be lower (or at least not higher) for each section of pipe before it reaches its final destination. [5]
Robert Maillart, c. 1925. Robert Maillart (16 February 1872 – 5 April 1940) was a Swiss civil engineer who revolutionized the use of structural reinforced concrete with such designs as the three-hinged arch and the deck-stiffened arch for bridges, and the beamless floor slab and mushroom ceiling for industrial buildings.
Headwall and corrie lake Cwm Idwal. In physical geography and geology, the headwall of a glacial cirque is its highest cliff.The term has been more broadly used to describe similar geomorphic features of non-glacial origin consisting of a concave depression with convergent slopes typically of 65 percent or greater forming the upper end of a drainage valley.

The two-lane road is 27 feet (8.2 m) wide, running inside the arches with two 3.5-foot (1.1 m) sidewalks.
