A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents for purposes such as providing agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools.

U.S. Route 80 (US 80) also known as the Ocean-to-Ocean Highway, the Broadway of America and the Jefferson Davis Memorial Highway was a major transcontinental highway that existed in the U.S. state of Arizona from November 11, 1926, to October 6, 1989. At its peak, US 80 traveled from the California border in Yuma to the New Mexico state line near Lordsburg. US 80 was an important highway in the development of Arizona's car culture. Like its northern counterpart, US 66, the popularity of travel along US 80 helped lead to the establishment of many unique road side businesses and attractions, including many iconic motor hotels and restaurants. US 80 was a particularly long highway, reaching a length of almost 500 miles (800 km) within the state of Arizona alone for most of the route's existence.
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the Grand Canyon. It turns south near Las Vegas, Nevada, forming the Arizona–Nevada border in Lake Mead and the Arizona–California border a few miles below Davis Dam between Laughlin, Nevada and Needles, California before entering Mexico in the Colorado Desert. Most of its waters are diverted into the Imperial Valley of Southern California. In Mexico its course forms the boundary between Sonora and Baja California before entering the Gulf of California. This article describes most of the major features along the river.

The Antelope Hill Highway Bridge is a historic bridge over the Gila River in Tacna, Arizona, U.S. It was built between 1914 ad 1915 as a ten-span concrete girder bridge. The bridge served as an integral piece of the Ocean to Ocean Highway between Yuma and Phoenix from 1915 to 1922, when it was bypassed by an alternate route through Gila Bend, paralleling the Gillespie Dam. The bridge and original highway were bypassed mainly due to damage caused by flooding along the river floodplain it was constructed on. After being repurposed for traffic traveling north from Yuma, the bridge was finally abandoned in 1929 following completion of the McPhaul Suspension Bridge. The ruins of the old bridge are currently listed on the National Register of Historic Places.
The Ocean-to-Ocean Bridge is a through truss bridge spanning the Colorado River in Yuma, Arizona. Built in 1915, it was the first highway crossing of the lower Colorado and is the earliest example of a through truss bridge in Arizona. It is also the only example of a Pennsylvania truss within Arizona. Originally the bridge carried the transcontinental Ocean-to-Ocean Highway and later carried its successor, US 80 until a new bridge was built to the west in 1956. Between 1988 and 2001, the bridge was closed to vehicular traffic and only traversable by pedestrians and bicyclists. After a major restoration, the bridge was rehabilitated and reopened to vehicular traffic in 2002, with a re-dedication by the Quechan nation and Yuma Crossing National Heritage Area. The bridge became part of Historic US 80 in 2018.
