caption_attribution_description: Jackknife Bascule Bridge being raised to let a boat pass. The bridge was completed in 1913 and carries Canadian Pacific Railway tracks. For many years it was a two-level bridge, carrying road traffic on an upper deck, but the upper deck was closed in 2003 and removed in 2004.
context_page_description: The Jackknife Bascule Bridge is a bascule bridge that spans the Kaministiquia River at Thunder Bay, Ontario, Canada, to link the city to Mission Island, one of two islands in 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. The bridge had two decks, the lower deck for trains and the upper deck for vehicular road traffic.
  The vehicular portion of the bridge was replaced by the Island Drive Bridge, which connects neighbouring McKellar Island to the mainland, in 2003. The connecting roadways and upper deck of the Jackknife Bridge were dismantled in 2004, but the lower deck continues to function as the only rail link to the islands.
