KAWARTHA LAKES-The opening of the Bobcaygeon swing bridge has been delayed once again.
Until recently, Parks Canada said they were hoping to re-open the bridge to traffic temporarily at the end of July.
In addition to a delay in both the design work and the delivery of hydraulic components due in part to COVID-19 restrictions, some structural parts on the bridge were in worse condition than expected according to Parks Canada. These factors have resulted in delays to the overall schedule.
Additionally, Parks Canada says they were recently advised that the Contractor is unable to submit quality control documentation for the fabrication of some key mechanical components. Mechanical components consist of things like the fasteners, wheels, locking pins, and centre pivot bearings, which are essential components that allow the bridge to be moved. Officials say the quality control documents in question are key to the delivery of the project as they demonstrate that the mechanical components were fabricated in accordance with both the contract and industry standards.
“The missing or non-compliant documentation is unusual, and raises concerns for the overall quality of the individual components as they relate to the safety and reliability of the rehabilitated bridge.” says Parks Canada.
As such, Parks Canada will not allow the installation of these components, and has instructed that they are re-fabricated.
The re-fabrication of components will take an additional 10-12 weeks; this is completed at an offsite machining shop and can begin during the navigation season. Following the closing of the navigation season in October, the contractor will complete the installation of hydraulic components, as well as completion of electrical work. The bridge is expected to re-open for vehicular traffic in December 2021.
A full testing of the swinging operation will take place in the spring, when seasonal temperatures better represent normal operational conditions, and are optimal for the movement of hydraulic fluids. This testing may result in temporary and short closures in spring 2022.
