MURRAY MACKAY BRIDGE
Location:Halifax, NS, Canada Description:Designed by Roger Dorton of Pratley & Dorton, the Murray MacKay Bridge was the first suspension bridge in North America to have an orthotropic steel deck, and the first in the world to utilize the deck as the top chord of the stiffening trusses. It was the first bridge ever to be wind tunnel tested in turbulent flow, a technique pioneered at the Boundary Layer Wind Tunnel under the direction of Dr. A. G. Davenport. Murray MacKay Bridge was constructed in 1970. Its main span measures 426 m (1400 ft.) and its total length is 1.2 km (7250 ft.). Dr. Dorton later became the manager of Buckland & Taylor Ltd.'s Ontario office, which closed upon his recent retirement. Owner/Client:Halifax-Dartmouth Bridge Commission Scope of Work:Since 2004, Buckland & Taylor Ltd. has provided advice to the Owner on various maintenance matters and modifications
that are extending the useful life of the bridge.
In 2005, Buckland & Taylor Ltd. performed an annual inspection. In 2006, Buckland & Taylor Ltd. completed an "analysis and survey" health analysis of the bridge,
conducted a study of safety levels for ships' clearance under the bridge, and provided various other engineering services.
In 2007, Buckland & Taylor Ltd. designed maintenance catwalks and in 2008 designed the replacement of selected bearings. For more information on our bridge engineering services, please Contact Us. |
