This unique stone arch crosses Minneopa Creek, just southwest of Mankato.
The bridge was built at two times. The 1879 portion was built for the railroad, which used the grade that the existing road uses. This span was completed on March 24th, 1879.
The railroad was relocated, and the arch was extended in 1905. The State of Minnesota reused the old grade and turned it into US-169, which was turned into a county road (now County 69).
The bridge contains a massive angle in the middle, adding to the unique structure.
Today, the stone arch is accessed from Minneopa State Park, or local foot trails.
It is also just downstream of Minneopa Falls, a local attraction.
The bridge was rehabilitated in 2014, with a new floor and lower walls. This should extend the lifespan by many decades.
Overall, this bridge remains in good condition.
The author has ranked this bridge as being moderately significant, due to the unique features of the bridge.
