Nepesta Bridge, Spanning Arkansas River on County Road 613, Boone, Pueblo County, CO

Significance: The only roadway truss left in Pueblo County over the Arkansas River after the 1921 flood, the bridge has served as a regionally important crossing on the major east-west artery in southeast Colorado for decades. It is a typically configured and structurally unaltered example of the early mainstay truss type, the pin-connected Pratt through truss. Placed in a rural setting beside a through girder of the Atchison Topeka and Santa Fe Railway, it is an important early vehicular bridge.
