Summary
Significance: The Four Mile Bridge is one of only two rigid connected Pennsylvania Through trusses with substruts still functional on the state and county roads in Wyoming. With a simple span of 175 feet, it is the longer of the two. As such, it is an uncommon truss type for a highway bridge, more usually associated with railroad spans, and is one of Wyoming's more significant trusses.
