Truss bridges are generally made from either steel or timber or a combination of both. Basically, this is a bridge with a timber truss which you drive through. The Bell Irving River Bridge is a steel truss bridge.
Like the Oyster River Bridge, you drive through the trusses, but in this example, those trusses are constructed of steel instead of timber.
If you look closely at this image, you will notice that this bridge has a metal deck used to reduce the weight of the bridge. The Simon Fraser Bridge, built inis a deck over steel truss bridge which with an arch shaped bottom profile spans the Fraser River in Prince George. It was twinned with a second bridge in Arch Bridges Are steel or concrete bridges constructed in the form of an arch or arches, typically with concrete abutments. Big Qualicum Bridge is concrete arch bridge with concrete girders located along Highway 19 on Vancouver Island.
Dry Gulch Bridge on Highway 5 is a steel arch bridge. Chilcotin BridgeLike the Dry Gulch Bridge featured above, the Chilcotin Bridge located in the Cariboo region is another classic example of a steel arch bridge. Unlike Dry Gulch Bridge, this arch uses a truss configuration.
The Culliton Bridge is a tied steel arch with the arch above the bridge deck.

Truss bridges appeared very early in the history of modern bridges. Truss bridges were built mostly of wood in the early s and slowly shifted to iron construction by the middle of that century. Steel became the standard by the s.

Some states continued building steel truss bridges through the s, while others abandoned them sooner, choosing to build concrete girder and beam bridges instead. Some truss bridges are extremely plain and utilitarian, while others use more elaborate design details. Throughout history, engineers experimented with different forms of truss bridges, trying to find better ways to solve particular problems.
A truss bridge can have a deck or roadbed on top deck trussin the middle through trussor at the bottom of the truss. If the sides of the truss extend above the roadbed but are not connected, it is called a pony truss or half-through truss.
Truss bridges are crossed by pedestrians, automobiles, trucks, light rail, and heavy rail. Truss bridges have historically been used to carry water and sewage through pipes across spans. Over the years, electrical and cable lines were added as well. Check out these examples.
