By fixing the superstructure at one end, while allowing the other end of a span to move freely in the longitudinal direction, thermal stresses are alleviated and the lifespan of the bridge increased. A concrete girder bridge pier during construction prior to installation of the bridge deck and parapets, consisting of multiple angled pylons for ...
The (non-modular) box girder bridge was a popular choice during the roadbuilding expansion of the 1960s, especially in the West, and many new bridge projects were in progress simultaneously. A serious blow to this use was a sequence of three serious disasters, when new bridges collapsed in 1970 ( West Gate Bridge and Cleddau Bridge ) and 1971 ...
A concrete curved-chord through girder bridge, sometimes known as a camelback bridge, [2] [i] is a type of concrete bridge most common in the U.S. state of Michigan and the Canadian province of Ontario. [1] C.V. Dewart, the first professional bridge engineer of the Michigan State Highway Department, designed the type. [3]

Quezon Bridge is a combined arch and prestressed concrete girder bridge crossing the Pasig River between Quezon Boulevard in Quiapo and Padre Burgos Avenue in Ermita in Manila, Philippines. Quezon Bridge was built to take the much greater and heavier 20th-century vehicular traffic than the 19th-century Puente Colgante , which it replaced.
Prestressed concrete is a major advance in concrete engineering and has effectively been used in rigid frame bridge construction. [10] This is notable because it was already challenging to place standard reinforcing in a concrete rigid frame bridge. Prestressing the rebars is more difficult but was proven to still be feasible. [10]
In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...
The four-span, concrete girder bridge, simply supported continuous-over-pier bridge on a 26 degree skew, is supported on three internal piers and abutments on both ends. The north end is anchored on to the abutment and the remaining supports have rocker bearings to allow movement to the bridge deck.
