Lafarge Canada was the prime contractor on the Mountain Highway Interchange project, a highly complex 4-direction interchange project that improved traffic throughout the community. Of the $198M total project value, Lafarge was responsible for construction valued at $60 M.
The scope of work included:
- Construction of on/off ramps in all four quadrants
- Signalization at both ends of the new structure to provide the safe movement of traffic on and off Mountain Highway
- Replacement of the existing two-lane Mountain Highway underpass with a new four-lane structure
- Full intersection at Keith Road/Brooksbank Ave/Mountain Highway
- New realigned Mountain Highway
The design will include overall improvements and expansion of facilities for alternate modes of transportation.
Most projects of this scale have a few noteworthy elements critical to the overall success. Aside from the usual challenges involving quality assurance and strategic traffic management in a high-traffic volume urban area, the following are some of the aspects the Lafarge team needed to consider:
Innovation in design and construction was vital to delivering this project quickly with the lowest possible lifecycle cost.

By leveraging this network, the team successfully minimized the amount of truck traffic delivering materials to the job site from distant material sources. Furthermore, there were a few additional factors that were an essential part of the solution:
