The Ririe A Pegram Truss Railroad Bridge is a Pegram truss railroad bridge which crosses the Snake River 3 miles (4.8 km) north of Ririe, Idaho. The bridge, which carries a one-track section of the East Belt Branch, consists of two truss spans and is 420 feet (130 m) long by 18 feet (5.5 m) wide. The bridge was originally constructed for a crossing in Nyssa, Oregon in 1894 for the Union Pacific Railroad and was relocated to its current site in 1914, where it carried Oregon Short Line Railroad tracks. The bridge's Pegram truss design was the work of George H. Pegram, the chief engineer for Union Pacific; as Pegram held a patent on the design, all surviving Pegram truss bridges were commissioned during Pegram's tenure with the Union Pacific and Missouri Pacific railroads.[2]

The bridge was added to the National Register of Historic Places on July 25, 1997.[1]
