The ERT Bridge over Blacks Fork near Fort Bridger, Wyoming, was listed on the National Register of Historic Places in 1985 as part of a thematic study on early 20th century steel truss bridges in Wyoming. The ERT Bridge is a Warren pony truss bridge spanning 80 feet (24 m) with a width of 15.75 feet (4.80 m). Set on concrete abutments, the ERT Bridge was built around 1920 by Uinta County. It is an example of a transitional design from locally built bridges to standardized State designs
The DXN Bridge over the Little Missouri River is one of a group of thirty-one bridges in Wyoming that were collectively listed on the National Register of Historic Places as excellent examples of steel truss bridges of the early 20th century. The DXN Bridge is located in Crook County, Wyoming. It is a single-span of about 72 feet (22 m), an 8-bay Pratt pony truss on Crook County Road 18-200. It was built about 1920. The bridge is unique in lacking inclined end posts.
The ECS Bridge over Big Goose Creek was a bridge near Sheridan, Wyoming, that was built in 1914. It was a Pratt pony truss bridge built by the Canton Bridge Company of Canton, Ohio. The Canton Bridge Company built four steel bridges in Wyoming in 1914; when nominated to the National Register of Historic Places in 1982, the ECS Bridge was the only one of these surviving in its original location. It was 50 feet (15 m) long and 15 feet (4.6 m) wide.
The EDZ Irigary Bridge is a historic Pennsylvania truss bridge in southeastern Johnson County, Wyoming. The bridge was built in 1913 at Sussex, Wyoming, and moved in 1963 to Irigary Road. The bridge was listed on the National Register of Historic Places in 1985 as part of a Multiple Property Submission devoted to historic bridges in Wyoming.
The CKW Bridge over Powder River is a Pratt deck truss bridge near Arvada, Wyoming, which carries US 14/US 16 across the Powder River. The bridge was built from 1932 to 1933 by the W. P. Roscoe Company. The 452-foot (138 m) bridge has three continuous main spans and two shallow approach spans. It is the only continuous truss bridge still in use on a Wyoming road and one of only two deck truss bridges built on a major highway.
The EBF Bridge over Powder River is a bridge located near Leiter, Wyoming, which carries Sheridan County Road CN3-269 over the Powder River. The 201.5-foot-long (61.4 m) bridge has two spans: the first span is a Pratt through truss, while the second span is a Warren truss. Due to this configuration, the bridge has been called "one of [Wyoming's] more interesting vehicular trusses." The trusses in the bridge are connected rigidly rather than by pins; the bridge was built in a transitional period between the two designs and is an early example of rigid connections. The Gregg & Stout Bridge Company of Sheridan built the bridge in 1915.
The ENP Bridge over Green River is a historic bridge located near Daniel, Wyoming, which carries Sublette County Road CN23-145 across the Green River. The Western Bridge and Construction Company built the bridge circa 1905. The 221-foot-11-inch (67.64 m) bridge has two spans, both Pratt trusses; the longer span is a Pratt through truss, while the shorter is a Pratt pony truss. The use of both through and pony trusses in the same bridge was uncommon in Wyoming, and the bridge is the only surviving example of a Pratt truss bridge in this style.
The ETD Bridge over Green River is a steel girder bridge near Fontenelle, Wyoming, which carries Sweetwater County Road CN4-8SS over the Green River. The bridge is a replacement for a historic Pratt through truss bridge built in 1913 by the Colorado Bridge and Construction Company. The 150-foot-long (46 m) bridge was one of the longest Pratt through truss bridges built in the early stages of Wyoming bridge construction.
The ETR Big Island Bridge is a Pratt through truss bridge located near Green River, Wyoming, which carries Sweetwater County Road CN4-4 across the Green River. The bridge was built from 1909 to 1910 by contractor Charles G. Sheely. It was named the Big Island Bridge after the Big Island region of Wyoming, which the bridge connected to other parts of the state. The 352-foot (107 m), two-span bridge is one of the older Pratt through truss bridges in Wyoming, and its spans, each 155 feet (47 m) long, are some of the longest on bridges of this design in the state.
The DDZ Bridge over New Fork River is a Kingpost pony truss bridge located near Boulder, Wyoming, which carries Sublette County Road 136 across the New Fork River. The bridge was built in 1917 by Lincoln County's government, as Sublette County had not yet been formed. Unlike most truss bridges at the time, the bridge was built with timber trusses rather than steel; it is the only wooden two-span Kingpost truss bridge remaining in Wyoming. The bridge's construction is considered to be "the most sophisticated" of extant wooden truss bridges in the state.
The DFU Elk Mountain Bridge was a Warren pony truss bridge located near Elk Mountain, Wyoming, which carried Carbon County Road 120-1 over the Medicine Bow River. The bridge was built in 1823 by contractor D. B. Miller. While the bridge's design is mainly a Warren truss, the top chord of the bridge is reminiscent of a Parker truss. At 102 feet (31 m) long, the bridge is the longest of its design in the Wyoming county highway system.
The DMJ Pick Bridge is a Parker through truss bridge located near Saratoga, Wyoming, which carries Carbon County Road CN6-508 across the North Platte River. The bridge was built from 1909 to 1910 by contractor Charles G. Sheely; it was originally located south of Fort Steele. In 1934, the bridge was moved up the river to its current location, as a new bridge had been built at its original site five years earlier. The bridge is the only Parker truss bridge remaining in Wyoming, after the Arvada Bridge was replaced in 1990.
The DML Butler Bridge is a historic bridge over the North Platte River in Carbon County, Wyoming, United States, that is listed on the National Register of Historic Places (NRHP).
The DOE Bridge over Laramie River was a Pratt half-hip pony truss bridge located near Bosler, Wyoming, which carried Albany County Road CNA-740 across the Laramie River. The bridge was built in 1926 by contractor N. A. Swenson; it was originally part of the Lincoln Highway. In 1932, the bridge was replaced and moved to its current location. It was the last two-span Pratt half-hip truss bridge remaining in Wyoming.
The DUX Bessemer Bend Bridge was a Warren through truss bridge in Bessemer Bend, Wyoming, which carried Natrona County Road CN1-58 across the North Platte River. The bridge was built from 1921 to 1922. When nominated to the National Register of Historic Places in 1982, it was one of only three Warren through truss bridges remaining on Wyoming county highways. In addition, the bridge was located at the site of a historic river crossing on the Oregon Trail.
The EJE Bridge over Shell Creek is a Warren pony truss bridge located near Shell, Wyoming, which carries Big Horn County Road CN9-57 across Shell Creek. The bridge was built in 1920 by the Midland Bridge Company, the only firm to bid for the bridge contract. At 60 feet (18 m) long, it is the longest known example of a Warren pony truss bridge in Wyoming.
The EJZ Bridge over Shoshone River is a Warren pony truss bridge located near Lovell, Wyoming, which carries Big Horn County Road CN9-111 across the Shoshone River. Contractors McGuire and Blakeslee built the bridge from 1925 to 1926 using a design by the Wyoming Highway Department. The 389-foot-6-inch (118.72 m) bridge has four spans, the second-most of any truss bridge in Wyoming.
The ELS Bridge over Big Wind River is a pony truss bridge located near Dubois, Wyoming, which carries Fremont County Road CN10-21 across the Big Wind River. The bridge was built circa 1920. Its design is uncommon and merges a kingpost truss with an arched chord. The materials used to build the bridge are also unusual and were likely salvaged; for instance, the arches are made from tunnel sets.
The ELY Wind River Diversion Dam Bridge is a Warren pony truss bridge located near Morton, Wyoming, USA, which carries Fremont County Road CN10-24 across the Wind River. The bridge's structure is integrated with the Wind River Diversion Dam. It was the first truss bridge to be connected with a dam during its construction. The Taggart Construction Company built the bridge from 1924 to 1925. The bridge is 655 feet (200 m) long and has eight spans, making it both the longest road truss bridge in Wyoming and the road bridge with the most spans in the state.
The New Hampton Pony Pratt Truss Bridge is a historic pony Pratt truss bridge on Shoddy Mill Road in New Hampton of Lebanon Township, Hunterdon County, New Jersey. It crosses the Musconetcong River between Lebanon Township, Hunterdon County and Washington Township, Warren County. It was designed by Francis C. Lowthorp and built in 1868 by William Cowin of Lambertville, New Jersey. The bridge was added to the National Register of Historic Places on July 26, 1977 for its significance in engineering, industry and transportation. It is one of the few early examples of iron Pratt truss bridges remaining in the United States. It was later documented by the Historic American Engineering Record in 1991. It was added as a contributing property to the New Hampton Historic District on April 6, 1998.
