Description 

The Bonanza Bridge is an example of a pin-connected Whipple through truss used for longer span crossings between 1850 and 1900. The Whipple truss design utilized for the Bonanza Bridge is one of only three such structures known to still exist in Missouri, thereby making it one of the most significant bridges in Missouri's historic bridge inventory. It is now known who fabricated the bridge.
