ETR Big Island Bridge

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.[2]
