The Champlain Bridge was a steel truss cantilever bridge with approach viaducts constructed of prestressed concrete beams supporting a prestressed concrete deck paved with asphalt. The bridge crossed the Saint Lawrence River, connecting the Island of Montreal to its South Shore suburbs.
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service.
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.
The Bolte Bridge is a large twin cantilever road bridge in Melbourne, Victoria, Australia. The Bolte Bridge carries a total of eight lanes of traffic – four lanes northbound and four lanes southbound. While officially only 490 metres in length, the actual structure appears much longer as it forms part of a 5 kilometre elevated roadway between Flemington Road and the West Gate Freeway. It spans the Yarra River and Victoria Harbour in the Docklands precinct to the west of the Melbourne CBD. It forms part of the CityLink system of toll roads that connects the Tullamarine Freeway from the northern suburbs with the West Gate Freeway and the Domain and Burnley tunnels to the Monash Freeway and the south eastern suburbs. It is named after Victoria’s 38th and longest-serving Premier, Sir Henry Bolte.
Mahatma Gandhi Setu is a bridge over the river Ganges in Bihar, India, connecting Patna in the south to Hajipur in the north. Its length is 5,750 metres (18,860 ft) and it is the third-longest river bridge in India. It was inaugurated in May 1982 in a ceremony in Hajipur by the then prime minister, Indira Gandhi. From 1982 to 2017, Mahatma Gandhi Setu remained as the longest bridge in India. Later, Gandhi Setu rehabilitation project was undertaken to install triangular steel trusses on Mahatma Gandhi Setu.
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
The West End Bridge is a steel tied-arch bridge over the Ohio River in Pittsburgh, Pennsylvania, approximately 1 mile (1.6 km) below the confluence of the Allegheny and Monongahela Rivers. It connects the West End to the Chateau neighborhood on the North Side of Pittsburgh.
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.
The George C. Platt Memorial Bridge is a through truss bridge that carries PA 291 over the Schuylkill River in Southwest Philadelphia, Pennsylvania. It was opened to traffic in 1951, replacing a swing bridge to the south which carried Penrose Ferry Road across the river. Originally called the Penrose Avenue Bridge, it was renamed in 1979 to honor Civil War hero George Crawford Platt (1842–1912). Today, the Platt Bridge is a key arterial route which carries an average of 56,000 vehicles daily.
The Hares Hill Road Bridge is a single-span, wrought iron, bowstring-shaped lattice girder bridge. It was built in 1869 by Moseley Iron Bridge and Roof Company and is the only known surviving example of this kind. The bridge spans French Creek, a Pennsylvania Scenic River.
The Walnut Lane Bridge is a concrete arch bridge located in Northwest Philadelphia that connects the Germantown and Roxborough neighborhoods across the Wissahickon Creek in Fairmount Park. While drivers may cross the bridge too quickly to notice, the view from underneath the bridge has inspired many artists and writers, such as Christopher Morley. The design was copied from Pont Adolphe in Luxembourg.
The Nyali Bridge is a concrete girder bridge connecting the city of Mombasa on Mombasa Island to the mainland of Kenya and located on B8 road. The bridge crosses Tudor Creek to the north-east of the island. The bridge is one of three road links out of Mombasa. The Likoni Ferry provides a third transport link to the island, and is situated at the southern tip. The mainland approach to the bridge serves as a police checkpoint in both directions.
The Wissahickon Memorial Bridge, originally called and still also known as the Henry Avenue Bridge, is a stone and concrete bridge that carries Henry Avenue over Wissahickon Creek and Lincoln Drive in Fairmount Park in Philadelphia, Pennsylvania.
The Godavari Arch Bridge is a bowstring-girder bridge that spans the Godavari River in Rajahmundry, India. It is the latest of the three bridges that span the Godavari river at Rajahmundry. The Havelock Bridge being the earliest, was built in 1897, and having served its full utility, was decommissioned in 1997. The second bridge known as the Godavari Bridge is a truss bridge and is India's third longest road-cum-rail bridge crossing a water body.
Kingsland Avenue Bridge, earlier known as Avondale Bridge and designated the De Jessa Memorial Bridge, is a vehicular movable bridge over the Passaic River in northeastern New Jersey. It crosses the county line to connect the towns of Lyndhurst in Bergen and Nutley in Essex, originally taking its name from the Kingsland section. The bridge is 10.7 miles (17.2 km) from the river's mouth at Newark Bay, and is required to open on four hours' notice. As of 2010, there were 26,420 daily crossings of the bridge, which provides one lane in each direction.
A Rigid-frame bridge is a bridge in which the superstructure and substructure are rigidly connected to act as a continuous unit. Typically, the structure is cast monolithically, making the structure continuous from deck to foundation. The connections between members are rigid connections which transfer bending moment, axial forces, and shear forces. A bridge design consisting of a rigid frame can provide significant structural benefits, but can also be difficult to design and/or construct.
A double tee or double-T beam is a load-bearing structure that resembles two T-beams connected to each other side by side. The strong bond of the flange and the two webs creates a structure that is capable of withstanding high loads while having a long span. The typical sizes of double tees are up to 15 feet (4.6 m) for flange width, up to 5 feet (1.5 m) for web depth, and up to 80 feet (24 m) or more for span length. Double tees are pre-manufactured from prestressed concrete which allows construction time to be shortened.
The Long Key Bridge, officially known as the Dante B. Fascell Bridge, is a bridge in the Florida Keys connecting Long Key and Conch Key, roughly halfway between Miami and Key West. At a length of nearly two and a half miles, it is the second longest bridge on the Overseas Highway after the Seven Mile Bridge. The current bridge opened in 1982, replacing the parallel Long Key Viaduct, which carried the Overseas Railroad from 1907 to 1935 and was repurposed for highway use shortly after.
Aquetong Creek is a tributary of the Delaware River in Solebury Township and New Hope, Bucks County, Pennsylvania. Rising from the Aquetong Spring, now known as Ingham Spring, just south of the intersection of U.S. Route 202, Lower Mountain Road, and Ingham Road, it runs about 10.75 miles (17.30 km) to its confluence with the Delaware.
