The Tasman Bridge is a prestressed concrete girder bridge connecting the Tasman Highway over the River Derwent in Hobart, Tasmania, Australia. When it opened on 29 March 1965, the Tasman was the longest prestressed concrete bridge in Australia, with a total length measuring 1,396 metres (4,580 ft), including approaches. The bridge provides a vital link between Hobart's city centre on the western shore and the City of Clarence on the eastern shore. Averaging 73,029 vehicle crossings per day, the bridge is the highest volume road section in Tasmania. It features five lanes of traffic including a central lane equipped for tidal flow operations and separated shared-use walkways on both sides, with ramp upgrades for improved access and cyclists completed in 2010.
The Sunshine Skyway Bridge, sometimes referred to as the Bob Graham Sunshine Skyway Bridge, the Sunshine Skyway, or simply "the Skyway", is a pair of long beam bridges with a central tall cable-stayed bridge that spans Lower Tampa Bay to connect Pinellas County to Manatee County. The current Sunshine Skyway opened in 1987 and is the second bridge of that name on the site. It was designed by the Figg & Muller Engineering Group and built by the American Bridge Company. The bridge is considered the flagship bridge of Florida and serves as a gateway to Tampa Bay. The four-lane bridge carries Interstate 275 and U.S. Route 19, passing through Pinellas County, Hillsborough County and Manatee County. It is a toll bridge, with a toll assessed on two-axle vehicles traveling in either direction at a rate of $1.75 cash or $1.16 with the state's SunPass system.
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.

Interstate 275 (I-275), located in Florida, is a 60-mile-long (97 km) auxiliary Interstate Highway serving the Tampa Bay area. Its southern terminus is at I-75 near Palmetto, where I-275 heads west towards the Sunshine Skyway Bridge crossing over Tampa Bay. From that point, I-275 passes through St. Petersburg before crossing Tampa Bay again on the Howard Frankland Bridge, then continues through the city of Tampa, where it connects to an interchange with I-4 in Downtown Tampa. After the interchange, I-275 passes north through the Tampa suburbs to its northern terminus at I-75 in Wesley Chapel.

The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts. The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland. The span replacement took place between 2002 and 2013, and is the most expensive public works project in California history, with a final price tag of $6.5 billion, a 2,500% increase from the original estimate of $250 million, which was an initial estimate for a seismic retrofit of the span, not the full span replacement ultimately completed. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. With a width of 258.33 ft (78.74 m), comprising 10 general-purpose lanes, it is the world's widest bridge according to Guinness World Records.
The Tasman Bridge disaster occurred on the evening of 5 January 1975, in Hobart, the capital city of Australia's island state of Tasmania, when the bulk carrier Lake Illawarra, travelling up the Derwent River, collided with several pylons of the Tasman Bridge and caused a large section of the bridge deck to collapse onto the ship and into the river below. Twelve people were killed, including seven crew on board Lake Illawarra, and the five occupants of four cars which fell 45 metres (150 ft) after driving off the bridge. Hobart was cut off from its eastern suburbs, and the loss of the road connection had a major social impact. The ship's master was officially penalised for inattention and failure to handle his vessel in a seamanlike manner.
Gandy Bridge is the southernmost bridge spanning Old Tampa Bay from St. Petersburg, Florida to Tampa, Florida. The original 1924 span was dismantled in 1975.

It became known as the Friendship Trail Bridge and was demolished in 2016, after closing in 2008 due to hazardous conditions and several failed efforts to preserve the span. The third (1975) and fourth (1997) spans of the Gandy Bridge are currently being used for vehicle traffic.

It was also known as the Newport Rail Bridge, as it had a spur to Newport, Minnesota, and J.A.R. bridge, after previous owners Joan and Al Roman of Chicago. It was one of the few double-decker bridges on the Mississippi, with the top level formerly used for railroad traffic and the bottom level formerly used as a road crossing. It also was one of a few toll bridges in Minnesota, and one of the last remaining ones. It closed to rail traffic in 1980, and road traffic in 1999, when the toll was 75 cents. After closing, the bridge sat dormant in the open position for 10 years before being partially demolished in 2009.
