The International Falls–Fort Frances Border Crossing connects the cities of International Falls, Minnesota and Fort Frances, Ontario, at the Fort Frances–International Falls International Bridge.

However, significant cross-border traffic didn't occur until after the dam across the Rainy River was completed in 1905.

In 1912, the Fort Frances–International Falls International Bridge was completed.

Cars and trucks must cross the tracks at grade on both ends of the bridge.
