Burlington Bay James N. Allan Skyway

About

The Burlington Bay James N. Allan Skyway, originally called the Burlington Bay Skyway and simply known as the Burlington Skyway or The Skyway, is a pair of high-level freeway bridges (built in 1958 and 1985) spanning the Burlington Bay Canal. The Skyway, as it is locally known, is located in Hamilton and Burlington, Ontario, Canada, and is part of the Queen Elizabeth Way (QEW) highway linking Fort Erie with Toronto.

The 1958 steel bridge is a suspended deck through-arch truss bridge. The approach to the main span has elements of a through-truss bridge, but the arch shape takes the truss higher than the roadway deck, so hangers are used to suspend the deck from the arch truss. The truss bridge is 2,560 m (8,400 ft) long overall. The main span of 151 m (495 ft) is flanked by two back spans each 83.7 m (275 ft) long; there are 72 total approach spans, and the bridge has 36.7 m (120 ft) of vertical clearance below the bottom of the deck. The 1985 bridge, a conventional precast concrete box girder structure, is 335 m (1,099 ft) shorter. The roadway deck for each bridge is 30 m (97 ft) wide.
