I normally don't show the river bank, but I wanted to capture what is now filled up with water.

"This bridge is one of 24 historic bridges in the state chosen by MnDOT for long-term preservation." [BridgeHunter_1931]

The 402' (122m) long bridge has a main span of 196' (60m).
"The bridge is skewed at the pier, but not at the ends of the bridge as a result of the unusual bend the river made at the point where this bridge was located. To address this, the engineers aligned the pier with the flow of water, to both reduce obstruction to the river, and put less stress on the pier. However, the abutments were not built at a skew. This arrangement resulted in an unusual truss design, where on each span, one truss was 196 feet long and ten panels, while the other truss was 176 feet long and nine panels."

The previous bridge allowed steamboats to use the river all the way to Mankato, and it was pin connected.
