Niagara Falls Suspension Bridge Company fonds, 1875-1876, 1878, 1884

In 1846, the governments of Upper Canada and the State of New York initiated the creation of two companies that would be authorized to build a bridge over the Niagara River. The bridge was to be owned by both companies, respectively known as the Niagara Falls Suspension Bridge Company (Canadian) and the International Bridge Company (American). A suspension bridge was completed in 1848. This bridge was later replaced by a second suspension bridge that accommodated railways, built in 1853-54. However, the increasing weight of trains made it necessary for the bridge to be redesigned, and a third bridge was completed in 1886. Eventually, this bridge was replaced by a steel arch bridge, which was completed in 1897.
