What's the bridge connecting the US and Canada, opened in 1938?

The Thousand Islands bridge, which was completed in 1938, is actually a system of five bridges and the island roadways connecting them. The international span, which crosses a small rift between Wellesley Island in the US and Hill Island in Canada, is only 90 feet in length. A second, parallel span was built in 1959 to accommodate congestion at the ports of entry. The US and Canada border stations are located at the opposite ends of this span.
