There is no description on the back of this card. The legend on the front states:
PEACE BRIDGE, OVER NIAGARA RIVER, CONNECTING BUFFALO, N.Y. AND FORT ERIE, ONTARIO S-46
— The through truss section near the American bank of the Niagara River actually crosses over the Black Rock Canal. It was completed in 1927 as the first Great Lakes bridge between the US and Canada from Niagara Falls to Minnesota.
This image likely dates from the 1940s.
