The Marion Memorial Bridge was a 4-span metal truss bridge that formerly carried U.S. Route 41 in Marion County, Tennessee over the Tennessee River and Nickajack Lake. It was built in 1929. The main span was 369 feet (112 m), and the bridge had a total length of 1,870 feet (570 m). The bridge was listed on the National Register of Historic Places on October 25, 2007. The bridge featured an unusual truss configuration that is a hybrid of the Parker and K-Truss configurations. The bridge was replaced by a new concrete and box girder span that opened in November 2014, slightly delayed from its target completion date of August 2013 by conditions encountered in the construction of the replacemen…

The Arthur Ravenel Jr. Bridge (colloquially referred to as the Ravenel Bridge and the Cooper River Bridge) is a cable-stayed bridge over the Cooper River in South Carolina, US, connecting downtown Charleston to Mount Pleasant. The bridge has a main span of 1,546 feet (471 m), the seventh longest among cable-stayed bridges in the Western Hemisphere. It was built using the design–build method and was designed by Parsons Brinckerhoff. Since its opening in 2005 the bridge has been considered an icon of Charleston and is one of the city's most recognizable landmarks.

The Royal Albert Bridge is a railway bridge which spans the River Tamar in England, between Plymouth, Devon and Saltash, Cornwall. Its unique design consists of two 455-foot (138.7 m) lenticular iron trusses 100 feet (30.5 m) above the water and conventional plate-girder approach spans. Its total length is 2,187.5 feet (666.8 m). It carries the Cornish Main Line railway in and out of Cornwall and is adjacent to the Tamar Bridge, which opened in 1961 to carry the A38 road. The Royal Albert Bridge was designed by Isambard Kingdom Brunel. Surveying started in 1848 and construction commenced in 1854. The first main span was positioned in 1857 and the completed bridge was opened by Prince Albert…

Theoretical Analysis of Ultimate Main Span Length for Arch Bridge. The advancement of construction techniques and high-performance sustainable materials enables the increase of span length for arch bridge. It is of great importance to study the theoretical ultimate span length of arch bridge. Based on the parabolic and catenary arch axes, the analytical solutions of ultimate span length of arch bridge are solved using theoretical derivation accounting for the strength, in-plane stability and out-plane stability conditions, respectively. Then, the use of high-performance concrete, reactive powder concrete and high-strength steel is considered to study the relationship between theoretical ult…
