ERT Bridge over Black's Fork
 The ERT Bridge over Black's 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
