This picture shows the so-called American span of the Thousand Islands Bridge, which joins the USA and Canada across the St. Lawrence River between New York and southeastern Ontario. The bridge is actually five successive spans of different construction crossing the river by island-hopping.

The description states:
AMERICAN SPAN OF THE
THOUSAND ISLANDS INTERNATIONAL BRIDGE
One of the four bridges joining the United States and Canada at the 1000 Islands, Ontario, Canada.
–There is a discrepancy between the count of bridges on the card, and the total of five in other sources. This is because the card description does not count the small bridge at the international crossing.
This care likely dates from the 1960s.
