The bridge is a single-span steel beam stringer bridge, resting on I-beam pile abutments with concrete wings. The bridge is 26 feet (7.9 m) long. Built in 1917, it was one of the first bridges built in the county by county employees, rather than by hired bridge companies, and predates the formation of state highway department by two years. [2]
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid

Using fallen trees, stringer bridges can be built. Wood laminated by stress, glued, dowels, or nails lumber are good for panel bridges. New lumber and wood scavenged from buildings and railroad ties can be used to build stringer bridges. [3] A licensed engineer can help operators design a safe, appropriate timber bridge.
CPP and CPR techniques include slab stabilization, full- and partial-depth repair, dowel bar retrofit, cross stitching longitudinal cracks or joints, diamond grinding and joint and crack resealing. CPP and CPR methods, developed over the last 40 years, are used in lieu of asphalt overlays and bituminous patches to repair roads when longer ...

When a bridge deck is installed in a through truss, it is sometimes called a floor system. [1] A suspended bridge deck will be suspended from the main structural elements on a suspension or arch bridge. On some bridges, such as a tied-arch or a cable-stayed, the deck is a primary structural element, carrying tension or compression to support ...
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.
