The National Bridge Inventory (NBI) is a database, compiled by the Federal Highway Administration, with information on all bridges and tunnels in the United States that have roads passing above or below them. That is similar to the grade-crossing identifier number database, compiled by the Federal Railroad Administration, which identifies all railroad crossings. The bridge information includes the design of the bridge and the dimensions of the usable portion. The data is often used to analyze bridges and to judge their condition. The inventory is developed for the purpose of having a unified database for bridges to ensure the safety of the traveling public, as required by the Federal Aid Highway Act of 1968. It includes identification information, bridge types and specifications, operational conditions, bridge data including geometric data and functional description, and inspection data. Any bridge more than 20 ft long used for vehicular traffic is included.
The Connecticut Turnpike is a freeway and former toll road in the U.S. state of Connecticut; it is maintained by the Connecticut Department of Transportation (ConnDOT). Spanning approximately 128 miles (206 km) along a generally west–east axis, its roadbed is shared with Interstate 95 (I-95) for 88 miles (142 km) from the New York state border in Greenwich to East Lyme; I-395 for 36 miles (58 km) from East Lyme to Plainfield; and State Road 695 (SR 695) for four miles (6.4 km) from Plainfield to the Rhode Island state line at U.S. Route 6 (US 6) in Killingly. The turnpike briefly runs concurrently with US 1 from Old Saybrook to Old Lyme and Route 2A from Montville to Norwich.

Interstate 95 (I-95) is the main north–south Interstate Highway on the East Coast of the United States, running in a general east–west compass direction for 111.57 miles (179.55 km) in Connecticut, from the New York state line to the Rhode Island state line. I-95 from Greenwich to East Lyme is part of the Connecticut Turnpike, during which it passes through the major cities of Stamford, Bridgeport, and New Haven. After leaving the turnpike in East Lyme, I-95 is known as the Jewish War Veterans Memorial Highway and passes through New London, Groton, and Mystic, before exiting the state through North Stonington at the Rhode Island border.
The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967 and was Minnesota's third busiest, carrying 140,000 vehicles daily. It experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The NTSB cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets, and that additional weight on the bridge at the time contributed to the catastrophic failure.
The history of Greenwich, Connecticut, United States.
Moses Wheeler Bridge carries Interstate 95 over the Housatonic River between Stratford and the Devon section of Milford. The current bridge is a 14-span continuous girder and floorbeam structure that carries three lanes of traffic in each direction, with full inside and outside shoulders. The current bridge, completed in 2016, replaces a pre-existing structure that was completed as part of the original Connecticut Turnpike in 1958. The original bridge was a 34-span plate girder structure with a concrete deck with three 12-foot travel lanes in each direction and no shoulders. The central span of the original bridge over the river's navigation channel included a pin and hanger assembly, which are no longer used in bridge construction in the United States. Construction on the Moses Wheeler Bridge began in 1955 and opened on January 2, 1958.
A pin and hanger assembly is used to connect two plate girders of a bridge. These assemblies are used to provide an expansion joint in the bridge. One beam is set on a pier with a short section cantilevered out toward the next pier. The other begins underneath the anchor span, and has its far end resting on the next pier. The beams have holes directly above each other. The two holes are connected using hangers, a pair of connecting plates sandwiching the bridge girders. A pair of large steel pins through the plates and girder webbing provide the hinges, holding up the suspended span while allowing it to move longitudinally. Large washers are bolted to each end of the pin to retain the hangers. Exceptionally long spans may have two sets of girders cantilevered from opposite bridge piers with a third set of girders suspended by pin and hanger assemblies from both cantilevers.
The Riverside Avenue Bridge is the only cast-iron bridge in Connecticut and one of a small number still in use in the United States. It carries Riverside Avenue over the New Haven Line railroad tracks in the Riverside section of Greenwich, Connecticut. The bridge was part of an earlier span built in 1871 over the Housatonic River by the New York and New Haven Railroad, and when that bridge was replaced, part of it was erected in Riverside in 1895. It was placed on the National Register of Historic Places in 1977.
The Silver Bridge was an eyebar-chain suspension bridge built in 1928 which carried U.S. Route 35 over the Ohio River, connecting Point Pleasant, West Virginia, and Gallipolis, Ohio. Officially named the Point Pleasant Bridge, it was popularly known as the Silver Bridge for the color of its aluminum paint.
The Mianus River Railroad Bridge, also known as the Cos Cob Bridge, is a bascule drawbridge built in 1904 over the Mianus River, in Greenwich, Connecticut. It was listed on the National Register of Historic Places in 1987. The bridge carries the Northeast Corridor, the busiest rail line in the United States, both in terms of ridership and service frequency. It is operated by the Metro-North Railroad, successor to Conrail, Penn Central, and the New York, New Haven and Hartford Railroad, which erected it, and is owned by the Connecticut Department of Transportation.

Currently the bridge is part of the Northeast Corridor line, carrying rail traffic of Amtrak and Metro-North, as well as freight trains operated by the Providence & Worcester Railroad.
The Adomi Bridge is a latticed steel arch suspension bridge crossing the Volta River at Atimpoku in Ghana in West Africa. It is the first permanent bridge to span the Volta River, which drains south into the Gulf of Guinea, and is Ghana's longest suspension bridge. It provides the main road passage, just south of the Akosombo Dam, between the Eastern Region and the Volta Region of Ghana. It was opened in 1957 by Kwame Nkrumah, Ghana's first president. The iconic crescent-shaped arch bridge is featured in Ghanaian stamps and currency.
The Skagit River bridge is a through-truss bridge that was built in 1955 and connects the Skagit County cities of Mount Vernon and Burlington, providing a vital link between Vancouver, British Columbia and Seattle. It consists of four consecutive spans that are structurally independent. Only the northernmost span collapsed into the river; the adjacent span also sustained impact damage from the same vehicle, but not severe enough to result in a collapse. The overhead support structure was known to have been struck by a truck as recently as October 2012.
The East Washington Avenue Bridge refers to the bridges that have connected East Washington Avenue over the Pequonnock River in Bridgeport, Connecticut. Records state that a bridge was first constructed on the site in 1836, but no description of the bridge has been found. The second bridge was a truss swing design and underwent heavy repair and modernization in 1893. The third design was a movable Strauss underneath-counter weight deck-girder bascule bridge. The plans were drafted by James A. McElroy, using Joseph B. Strauss's design in 1916. However, construction was delayed for years because of a dispute with the contractor and a lack of funds. The bridge was completed by Bridgeport Dry Dock and Dredging when the State of Connecticut appropriated $350,000 to erect the bridge. Completed in 1925, the bridge underwent several modifications throughout its service life. On July 26, 1983, the bridge was closed after it was found to be in danger of collapse. It reopened after repair, but was closed in the 1990s before being replaced with a modern bascule bridge in 1998. In 2010, the report listed the deck and superstructure conditions as "Good" and the substructure condition as "Satisfactory".
The Allen Street Bridge was a bridge over the Cowlitz River between Kelso, Washington and Longview, Washington that collapsed on January 3, 1923, killing as many as 35 people. It resulted in the deadliest bridge collapse in Washington history.
