A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.

The John A. Roebling Suspension Bridge is a suspension bridge that spans the Ohio River between Cincinnati, Ohio, and Covington, Kentucky.

The Mazatzal Mountains are a mountain range in south central Arizona, about 30–45 miles northeast of the Phoenix metropolitan area. The origin of the name remains obscure but one possibility is that it is from the Nahuatl language meaning "place of the deer". The crest of the Mazatzals forms the county line between Maricopa County and Gila County. SR 87, the Beeline Highway, traverses the Mazatzals on its way to Payson. The highest peak is Mazatzal Peak at 7,903 feet (2,409 m). They also include the Four Peaks, with elevation 7,659 ft, 2,334 m; a prominent mountain and landmark of the eastern Phoenix area.

The 1950 Tacoma Narrows Bridge is a suspension bridge in the U.S. state of Washington that carries the westbound lanes of Washington State Route 16 across the Tacoma Narrows strait, between the city of Tacoma and the Kitsap Peninsula. Opened on October 14, 1950, it was built in the same location as the original Tacoma Narrows Bridge, which collapsed due to a windstorm on November 7, 1940. It is the older of the twin bridges that make up the Tacoma Narrows Bridge crossing of the Tacoma Narrows, and carried both directions of traffic across the strait until 2007. At the time of its construction, the bridge was, like its predecessor, the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and George Washington Bridge; it is now the 46th-longest suspension bridge in the world.
The Yale Bridge or Lewis River Bridge spans the Lewis River near Yale, Washington. It was built in 1932 by Cowlitz and Clark counties. The suspension bridge has a clear span of 300 feet (91 m), with a total length of 532 feet (162 m), replacing a previous steel truss bridge at the site. Construction of the Ariel Dam had created Lake Merwin with a water depth of 90 feet (27 m) at the site, requiring a new bridge that did not need to have support piers in the water. The road deck, stiffened by a steel Warren truss, is 50 feet (15 m) above the high water line of the reservoir.

The Gilsum Stone Arch Bridge carries Surry Road over the Ashuelot River in Gilsum, New Hampshire. Built in 1862–63, it is one of the highest stone arch bridges in the state. It has a span of 47 feet 8 inches (14.53 m), and an average height over the river of 36 feet 6 inches (11.13 m). The roadway is 43 feet 6 inches (13.26 m) above the riverbed. It stands on the site of four previous bridges, where the river passes through a deep gorge. The previous bridge was also a stone arch bridge, which was built in 1860 and collapsed a few months later. It was designed by William Leonard Kingsbury, a local official; its builders are not known because the town's records were destroyed in a fire. The present bridge's vault is carefully constructed from dry-laid granite voussoirs that were shaped for a very precise fit, with larger stones at the lower ends of the arch, and a smaller ones at the crown. Some of the stones were left with rough surfaces, while others were hammered smooth.
