The Smith River flows from the Klamath Mountains to the Pacific Ocean in Del Norte County in extreme northwestern California, on the West Coast of the United States. The river, about 25.1 miles (40.4 km) long, all within Del Norte County, flows through the Rogue River – Siskiyou National Forest, Six Rivers National Forest, and Jedediah Smith Redwoods State Park.
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.
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
The Jamestown Bridge was a cantilever truss bridge that connected Conanicut Island to mainland North Kingstown, Rhode Island, spanning the West passage of Narragansett Bay. The bridge first opened to traffic in 1940, replacing ferry service as the primary connection for the town of Jamestown, situated on Conanicut Island. It was constructed for just over $3 million 1940 USD, which was paid for by tolls until June 28, 1969. With a total length of 6,892 feet, the Jamestown Bridge was the third longest in Rhode Island at the time of its destruction, ranking behind its replacement, the adjacent 7,350-foot Jamestown Verrazzano Bridge, and the 11,248-foot Claiborne Pell Newport Bridge connecting Conanicut Island to Aquidneck Island and Newport. The Jamestown Bridge was closed to vehicular traffic on October 8, 1992, and its main span was destroyed through a controlled demolition on April 18, 2006.
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends.
A continuous truss bridge is a truss bridge which extends without hinges or joints across three or more supports. A continuous truss bridge may use less material than a series of simple trusses because a continuous truss distributes live loads across all the spans; in a series of simple trusses, each truss must be capable of supporting the entire load.
The Miami Bridge, also known as the McDaniel Memorial Bridge, is a new concrete girder bridge that was built to replace a cantilever through truss bridge over the Missouri River at Miami, Missouri between Saline County, Missouri and Carroll County, Missouri. The Miami Bridge carries Route 41. The Miami Bridge was built in 1939, and its deck was replaced in 1983 as part of a rehabilitation project. The old bridge's main cantilever span was 474.7 feet, while the two anchor spans were each 415 feet in length, resulting in a total cantilever truss length of 1304.7 feet. There were 11 approach spans, including four Warren deck truss spans, three on the northern approach and one on the southern approach. All remaining approach spans were steel stringer (multi-beam/girder) spans. Total bridge length including approach spans is 2,071.9 feet. The bridge's deck width is 23.0 feet and it has vertical clearance of 16.5 feet.
The Bryan Bridge brings U.S. Route 20 over the Niobrara River in Cherry County, Nebraska, near Valentine. It was built in 1932 and is a pin-connected arch bridge that is designated "Most Beautiful Steel Bridge" in its year, out of bridges costing less than $250,000, by the American Institute of Steel Construction. It is named after then-sitting Nebraska governor Charles W. Bryan.

It was listed on the National Register of Historic Places in 2007 as Bridge 6.
The Winooski River Bridge, also known locally as the Checkered House Bridge, is a historic Pennsylvania through truss bridge, carrying U.S. Route 2 (US 2) across the Winooski River in Richmond, Vermont.
