This is the nine span bridge at Caledonia, Ontario. If you can't read the fine print, it says, "Caledonia's famous nine span bridge, the only one of its kind in Canada."
The bridge was built between June 7th and November 19, 1927. That was a major feat back then. The bridge, over 80 years old, is 72 feet 7 inches in length. There was a two day celebration when it was declared open my government officials.
In 1984, major work was done on the bridge to reinforce it. Motorists still use the bridge today, even though a bypass has been constructed around the city.
I remember traveling over this bridge as a child and thinking how large it was. Back in the 50s, it was the biggest bridge I'd ever seen. It was thrill to cross the arched bridge and watch the water of the Grand River flow over the dam.
The picture was probably taken in the late 50s. The area has really built up since that time, but the bridge remains.
