Nipigon Cable

 

Solutions & Technologies

The new Nipigon River Bridge east of Thunder Bay, Ontario is the first cable-stayed structure on the Ontario TransCanada Highway system. The project started in 2013 on this four-lane, two-span bridge which will replace an aging, two-lane structure. The new bridge has three precast concrete towers with cables supporting a 252m bridge deck and separate sidewalk for pedestrians. The center pier reaches a height of 51m above the bridge deck.

 

Challenge

In a remote area frequently exposed to harsh environmental conditions, the project required the use of high and ultra-high performance materials such as Ductal® that provide superior strength and long-lasting durability. Key challenge was to ensure the material used for connections was able to achieve 80Mpa in less than 24hrs in order to maintain further section installation as the bridge was built from the center out towards the abutments. As such, the Ministry of Transportation Ontario (MTO) chose Ductal® ultra-high performance concrete Infrastructure solution for the connection of precast tower segments to cast-in-place tower segments and the connection of longitudinal and transverse joints to steel girders and beams. Importantly, the use of Ductal® on these structural connections also allows for rapid cable-stayed construction.

 

Partnership

The MTO (Northwestern Region) was a collaborator and pioneer in the early development and use of field-cast Ductal® connections in North America.

Bot Ferrovial Nipigon Joint Venture (BFNJV) managed the $106-million contract, with full completion in 2017. By the time it's done, this innovative project will have supported approximately 1,000+ jobs. According to Glen R. Murray, Minister of Transportation: "Our government is improving infrastructure across the province, which creates jobs and strengthens our economy. Projects such as this will help ensure our roads are safe and in good condition for years to come".
