Parsons Brinckerhoff has been awarded a contract to design the replacement of the controls, drives, and overhead cables at the Burlington Canal Lift Bridge.
In addition, the span drive machinery will be evaluated for partial replacements and retrofits.
The bridge connects Burlington and Hamilton at the western shore of Lake Ontario in Canada.
Parsons Brinckerhoff is responsible for carrying out the engineering design, contract administration, resident site services, commissioning and post-construction services for the project. Also included are all necessary structural engineering and other related services for the completion of the work.
Tendering for construction is scheduled to begin in May 2013, with completion in March 2015.
The Burlington Canal Lift Bridge, opened in 1962, is a steel truss vertical lift movable bridge originally designed to carry two lanes of vehicular traffic and one railway track for the Hamilton-Northwestern Railway across the Burlington Canal. The railway track was removed and the structure was modified to accommodate a widened roadway in 1982. The bridge now carries four lanes of vehicular traffic.
There is a lift span across the canal as well as one tower span and one approach span at each end of the bridge. The lift span is 117m long and 20m wide with a vertical lift of 33.5m to accommodate commercial shipping passage through the Burlington Canal. There is a footpath on the west side of the bridge for pedestrians.
Parsons Brinckerhoff was also part of the project team during the initial construction of the bridge. As a subconsultant to CC Parker, Parsons Brinckerhoff provided engineering for the control house, and for all mechanical and electrical systems.
