Gustave Eiffel: Alexandre Gustave Eiffel (born Bönickhausen; ; ] ; 25 December 1832 – 27 December 1923) was a French civil engineer and architect.  A graduate of École Centrale Paris, he made his name with various bridges for the French railway network, most famously the Garabit viaduct.  He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York.  After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields.

Abbotsford Bridge: Abbotsford Bridge is a steel Allan truss-type bridge spanning the Murray River between Curlwaa, New South Wales, and Yelta, Victoria.  It is the only remaining steel truss bridge with a lift span that crosses the Murray.  Opened in 1928, the bridge was built by the New South Wales (NSW) Department of Public Works and was designed by Percy Allan.  It was the second last lift-span bridge to be built over the river, the last being the Nyah Bridge, which opened in 1941.

Clyde Arc: The Clyde Arc (known locally as the Squinty Bridge), is a road bridge spanning the River Clyde in Glasgow, in west central Scotland, connecting Finnieston, near the Clyde Auditorium and SEC with Pacific Quay and Glasgow Science Centre in Govan.  A prominent feature of the bridge is its innovative curved design and the way that it crosses the river at an angle.  The Arc is the first city centre traffic crossing over the river built since the Kingston Bridge was opened to traffic in 1969.

Hite Crossing Bridge: The Hite Crossing Bridge is an arch bridge that carries Utah State Route 95 across the Colorado River northwest of Blanding, Utah, United States.

The bridge is the only automobile bridge spanning the Colorado River between the Glen Canyon Bridge, 185 mi downstream near the Glen Canyon Dam and the U.S. Route 191 bridge 110 mi upstream near Moab.  The bridge is near Hite Marina on Lake Powell, and a small airstrip is immediately adjacent to the north side of the bridge.

The bridge was designed and built in 1934 by the Vincennes Bridge Company, and carried Arkansas Highway 18 until 1998, when a modern 4-span I-beam bridge was built adjacent to it.  The old bridge was dismantled, leaving only the vertical lift segment on the east bank of the river.
