The Jackknife (or Jack-knife) Bascule Bridge spanning the Kaministiquia River at Thunder Bay, Ontario, Canada, linking the city to Mission Island, one of two islands that form the Kaministiquia River delta. The bridge was built by the Canadian Pacific Railway between August 1910 and April 1913. The contractor for the abutments and piers was Alexander Charles Stewart (1867-1944). The bridge has two decks, the lower deck for trains and the upper deck for vehicular road traffic.
The bridge was replaced by the Island Drive Bridge, which connects neighbouring McKeller Island to the mainland, in 2003. The connecting roadways and upper deck of the Jackknife Bridge were dismantled in 2004, and the future of the bridge is in doubt.
