Steel corrugated culvert with a drop on the exhaust end, northern Vermont. Culverts can be constructed of a variety of materials including cast-in-place or precast concrete (reinforced or non-reinforced), galvanized steel, aluminum, or plastic (typically high-density polyethylene). Two or more materials may be combined to form composite ...
Tunnel Construction. Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.

The channels are formed in large metal forms that (usually) have a pre-determined channel width, depth, and slope. Like in the cast-in-place method, a metal frame is attached to the form and concrete is poured and finished in a factory atmosphere. The advantage to the pre-cast trench drain is again time savings—big time savings at the job site.
A steel culvert bridge and a concrete culvert bridge were built across the creek in 1974 and 1976, respectively and another bridge was built in 2011. [7] Raven Creek is described as "quite a stream" in John Gosse Freeze's 1888 book A History of Columbia County, Pennsylvania: From the Earliest Times. [8]
