A historic rail lift bridge spanning the U.S.-Canada border near International Falls, Minnesota, and Fort Frances, Ontario, has collapsed, impacting water traffic on the Rainy River. The incident, which occurred on Wednesday, did not involve any trains and fortunately resulted in no injuries. The cause of the collapse is currently under investigation.

According to reports from the Minneapolis Star Tribune, environmental crews have managed to contain and recover some biodegradable, non-toxic hydraulic oil that was released as a result of the collapse. The Canadian National Railway is actively involved in these cleanup efforts.

The bridge, referred to as both the Rainy River Rail Lift Bridge and the 5 Mile Bridge, was constructed in 1908. It is a crucial structure as it swings up to allow passage for water traffic on the river, which acts as an international border running from Lake of the Woods to Rainy Lake.

Repairs have already commenced on the bridge, but it remains uncertain when the area will reopen for water traffic along the Rainy River. The age and significance of the bridge make the restoration efforts a priority to ensure the smooth flow of transportation between the two regions.
