King's Highway 61 is a provincially maintained highway in the Canadian province of Ontario that forms part of the Lake Superior Circle Tour. The 61-kilometre (38 mi) route extends from a junction at Highway 11, Highway 17 and the Harbour Expressway in Thunder Bay south to a bridge over the Pigeon River, where it crosses into the United States and becomes Minnesota State Highway 61. The roads on either side of the river were completed in 1916, but there was no bridge to connect them. Funding for a bridge over the international crossing at the Pigeon River required federal approval from both governments, but local civic groups in Port Arthur and Duluth expected that the process would be too slow, and built it without approval. The bridge was opened by a travelling motorcade in August 1917, permitting travel between Ontario and Minnesota. To the surprise of the civic groups, Canadian officials attending the opening announced federal funding to cover the bridge costs. (Full article...)
