SAINT JOHN HARBOUR BRIDGE
Location:Saint John, NB, Canada Description:The Saint John Harbour Bridge spans Saint John Harbour at the mouth of the Saint John River. The bridge, which carries four lanes of traffic, opened in 1968 and is 1.2 km (3,890 ft.) long. The bridge comprises two major structural forms. The 296 m (970 ft.) main and side spans (over the water) comprise twin variable depth box girders supporting an orthotropic steel deck in the main span and a concrete deck in the side spans. The approach spans comprise concrete deck on AASHTO girders. Owner/Client:Saint John Harbour Bridge Authority Scope of Work:Buckland & Taylor Ltd. (B&T) began work on the bridge by performing an overview inspection in 2007. Following on this, interim repairs were identified and B&T prepared contract documents and provided construction assistance. These repairs began in 2007, continued in 2008 and will be completed in 2009. B&T carried out a comprehensive design to rehabilitate the bridge deck over two years and prepared contract documents. This work was tendered and but was not awarded because funding was not secured. The current intent is to retender for construction to begin in 2010. B&T will provide construction services. B&T also carried out a load evaluation to Canadian Highway Bridge Design Code (CHBDC, CAN/CSA-S6-06) criteria. For more information on our bridge engineering services, please Contact Us. |
