A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported.
A plate girder bridge is a bridge supported by two or more plate girders.
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table. Each supporting frame is a bent. A trestle differs from a viaduct in that viaducts have towers that support much longer spans and typically have a higher elevation.
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. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although the box girder bridge is normally a form of beam bridge, box girders may also be used on cable-stayed and other bridges.
A girder is a beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. Girders are commonly used to build bridges.
The medium girder bridge (MGB) is a lightweight, man-portable bridge that can be assembled without help from heavy equipment. In addition, it is also a deck type, two-girder bridging system capable of carrying loads up to and including main battle tanks (MBT).
The M5 is an expressway in the City of Cape Town Metropolitan Municipality, South Africa. It connects Milnerton on the Western Seaboard in the north to Muizenberg in the south, and crosses both the N1 and the N2. For part of its length, from the N1 interchange to Plumstead, it is a limited-access freeway (motorway). From Mowbray to Muizenberg it is parallel to the M4 Main Road.
A tied-arch bridge is an arch bridge in which the outward-directed horizontal forces of the arch(es) are borne as tension by a chord tying the arch ends rather than by the ground or the bridge foundations. This strengthened chord may be the deck structure itself or consist of separate, independent tie-rods.
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box.
A box girder or tubular girder 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.
The Interstate 635 Bridge is an automobile crossing of the Kansas River in Kansas City, Kansas. The bridge was built in 1976, and work to rebuild it started 2003, and finished by 2005. During the rebuild process, the bridge underwent repairs, was resurfaced, and the girder beams were replaced in some places.
The U.S. 40 and 59 Bridges are twin multi-beam girder bridges over the Kansas River at Lawrence, Kansas. The west bridge carries two lanes of southbound traffic, connecting to Vermont Street, while the east bridge carries two lanes of northbound traffic from Massachusetts Street. Both bridges converge on the north end to become North 2nd Street. The east bridge is also the third bridge to be built at this location.
The Kansas Turnpike Bridges are a pair of multi-beam girder bridge that carry the Kansas Turnpike and Interstate 70 over the Kansas River at Lawrence, Kansas.
A deck is the surface of a bridge. A structural element of its superstructure, it may be constructed of concrete, steel, open grating, or wood. Sometimes the deck is covered by a railroad bed and track, asphalt concrete, or other form of pavement for ease of vehicle crossing. A concrete deck may be an integral part of the bridge structure or it may be supported with I-beams or steel girders.
A balloon flange girder is a form of vertical I-beam wrought iron plate girder, where the top flange, instead of being a simple flat plate, is extended into a hollow tube. When a girder is subjected to a positive bending moment the top flange acts in compression making a flat plate flange more susceptible to local buckling than the balloon flange is.
Marsh Creek is a tributary of Bowman Creek in Wyoming County, Pennsylvania, in the United States. It is approximately 5.6 miles (9.0 km) long and flows through Northmoreland Township, Eaton Township, and Monroe Township. The watershed of the creek has an area of 10.2 square miles (26 km2). The creek is not designated as an impaired waterbody. Wild trout naturally reproduce within it. The watershed of Marsh Creek is designated as a High-Quality Coldwater Fishery and a Migratory Fishery. The creek has several bridges crossing it.
The Passaic Street Bridge is a vehicular bridge crossing the Passaic River in Passaic and Garfield, New Jersey. The girder bridge was built in 1898 and is the third to span the river at that point. It is considered eligible for listing on the New Jersey Register of Historic Places and National Register of Historic Places.
The Yowaka River bridge is a heritage-listed road bridge that carries the Princes Highway across the Yowaka River at Greigs Flat, New South Wales, Australia. It was built in 1936. The bridge is also known as the Yowaka Bridge near Eden. The bridge is owned by Transport for NSW. It was added to the New South Wales State Heritage Register on 20 June 2000.
