Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. Constructed between 1931 and 1936, during the Great Depression, it was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over 100 lives. In bills passed by Congress during its construction, it was referred to as the Hoover Dam, after President Herbert Hoover, but was named the Boulder Dam by the Roosevelt administration. In 1947, the name Hoover Dam was restored by Congress.

A trolleytruck is a trolleybus-like vehicle used for carrying cargo instead of passengers. A trolleytruck is usually a type of electric truck powered by two overhead wires, from which it draws electricity using two trolley poles. Two current collectors are required in order to supply and return current, because the return current cannot pass to the ground since trolleytrucks use tires that are insulators. Lower powered trucks, such as might be seen on the streets of a city, tend to use trolley poles for current collection. Higher powered trucks, such as those used for large construction or mining projects, may exceed the power capacity of trolley poles and have to use pantographs instead. Trolleytrucks have been used in various places around the world and are still in use in cities in Russia and Ukraine, as well as at mines in North America and Africa. Because they draw power from the mains, trolleytrucks can use renewable energy sources – modern trolleytrucks systems are under test in Sweden and Germany along highways using diesel–electric hybrids to reduce emissions.
The Feather River Route is a rail line that was built and operated by the Western Pacific Railroad. It was constructed between 1906 and 1909, and connects the cities of Oakland, California, and Salt Lake City, Utah. The line was built to compete with the Central Pacific Railroad, which at the time held a nearly complete monopoly on Northern California rail service. The route derives its name from its crossing of the Sierra Nevada, where it follows both the North and Middle Forks of the Feather River. The route is famous for its impressive engineering qualities and its considerable scenic value. All of the route is now owned and operated by the Union Pacific Railroad; however, the Union Pacific has transferred significant portions of the route to other lines. The portion still called the Feather River Route by the Union Pacific runs from the California Central Valley to Winnemucca, Nevada and has been divided into three subdivisions named the Sacramento, Canyon and Winnemucca subdivisions.

The Uinta Basin Rail project is a proposed 100-mile (160 km) rail line to connect the shale oil rich Uinta Basin region of eastern Utah to the national rail network. Numerous proposals have been made, some as far back as 1902, that are still under consideration. The current effort is a public-private partnership between a coalition of 7 counties in Utah, the Rio Grande Pacific Corporation and Drexel Hamilton Infrastructure Partners. The railroad is also backed by the Ute Tribe who hold a 5% stake in the project. If the rail line is built it will be the first major greenfield rail line built in the United States since the Chicago and North Western’s line to the Powder River Basin was built in the early 1980s. The Surface Transportation Board approved construction of the line in December 2021, but in August 2023, a Federal Appeals Court halted the project pending "a more fulsome explanation for the Board’s conclusion that the Railway’s transportation benefits outweighed the project’s environmental impacts".
