Bridge trusses for bridge construction
The Warren truss, the Modified Warren truss, and the Pratt truss are the three major truss configurations in use today, and they can all be employed as an underslung truss, a semi-through truss, or a thro.

Qitai Large Span Bridge
The bridge over Hongshui River, situated in Tian'e County in Hechi City of Guangxi, is a two-way four-lane bridge with a total length of 2,488. It is the world's longest steel-reinforced concrete arch bridge in terms of span. [Photo/Xinhua]Spearheaded by Professor Jielian Zheng of Guangxi University and a member of the Chinese Academy of Engineering, the nation is delivering projects that don't just impress on paper but are breaking ground in more ways than one. Unlike previous record breaking arch spans that have always been made of steel, the Longtan Tianhu Bridge is made of concrete. Steel was only used internally as part of a skeleton core. At 11:00 on February 1, 2024, the world's largest span of stiff skeleton concrete arch bridge—Tian'e Longtan Grand Bridge of Guangxi Nandan-Tian'e Expressway was completed and opened to traffic, which is the world's first arch bridge with a span of more than 600 meters.

Bridge Frame Three-Way
A multi-way bridge is a with three or more distinct and separate spans, where one end of each span meets at a common point near the centre of the bridge. Unlike other bridges which have two entry-exit points, multi-way bridges have three or more entry-exit points. For this reason, multi-way bridges are not to be confused with commonly found road bridges which carry vehicles in one direction from one entry p.

Bridge Frame Slope Protection
Reinforced concrete slope paving or slope reinforcing is applied to the slopes under certain bridges to prevent erosion and to protect the soil around cap-type, spill-through, and sill-type abutments with either sweptback or elephant ear wingwalls. The goals of this project were to (1) develop guidance in identifying site conditions of over-water bridges which corresponded to performance issues associated with WisDOT's standard method for slope protection, and (2) to develop guidance for alternative protection methods at problematic sites. Concrete slope protection is normally provided on the head slopes of approach for a grade separation, or on slopes of river training works. They also improve the overall appearance of the. Slope protection structures are engineered features designed to mitigate the risks associated with soil erosion, landslides, and slope instability. Concrete Slope Protection shall include fine-grading the slope surface to a plane 100 mm below the specified.

Gabon-Bissau span bridge
The world's longest suspension bridges are listed according to the length of their main (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span th.
