A train derailment in southeastern Minnesota could be related to the failure of the wooden railroad bridge.
Department of Public Safety spokesman Doug Neville says it's not clear if the privately owned bridge collapsed under the train, or if derailed cars took it out.
He says the derailed train is owned by the Iowa, Chicago & Eastern Railroad, but it's also unclear if that railroad also owns the bridge.
A spokesman for the railroad did not immediately return a message left at his office.
The derailment caused ethanol to spill Tuesday morning on Highway 26 near Reno in southern Houston County, near the Iowa border.
No one was hurt and there are no evactuations. However, traffic is being stopped in Brownsville, Minnesota, and New Albin, Iowa, because of the potential danger.
