Parry Sound CPR Trestle
The Parry Sound CPR Trestle crosses the valley of the Seguin River, just upstream of the river's mouth at Parry Sound on Georgian Bay, as well as Great North Road, Bay, and Gibson streets in the town of Parry Sound, Ontario, Canada.
Completed in by the Canadian Pacific Railway, the trestle is long and high. The first scheduled train passed over the span in 1908. It is the longest rail trestle east of the Rocky Mountains.
In July 1914, Tom Thomson visited Parry Sound and painted the bridge and the former Parry Sound Lumber Company.
Today the trestle provides westbound rail traffic for both the Canadian Pacific Railway and the Canadian National Railway while all eastbound traffic uses Canadian National trackage. This sharing of resources was adopted by the competing companies as a way of alleviating congestion in Central Ontario.
