Sizing of a reline culvert uses the same hydraulic flow design criteria as that of a new culvert however as the reline culvert is meant to be inserted into an existing culvert or host pipe, reline installation requires the grouting of the annular space between the host pipe and the surface of reline pipe (typically using a low compression ...

A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete.
Hornell officials are planning a new Canisteo Street box culvert over Spencer Creek after getting $1.5 million from the state. Here's the timeline.
Baffles may be installed along the culvert to provide some fish-friendly alternative. [ 1 ] [ 2 ] But baffles can reduce drastically the culvert discharge capacity for a given afflux, [ 3 ] thus increasing substantially the total cost of the culvert structure to achieve the same design discharge and afflux, or increasing the risk of road ...
A culvert pipe under a road is a common target for beaver damming because the constriction speeds up the current and may resemble a hole in a dam. With a little work, a beaver can quickly plug a culvert with mud and sticks, and turn the entire roadbed into a large dam.
Products include: box culverts, 3-sided culverts, bridge systems, railroad crossings, railroad ties, sound walls/barriers, Jersey barriers, tunnel segments, concrete barriers, TVCBs, central reservation barriers, bollards, and other transportation products. Precast concrete can also be used to make underpasses, surface crossings, and pedestrian ...
A box girder or tubular girder (or box beam) is a girder that forms an enclosed tube with multiple walls, as opposed to an Ɪ-or H-beam. Originally constructed of wrought iron joined by riveting , they are now made of rolled or welded steel, aluminium extrusions or prestressed concrete .
