Some bridge replacement projects in Ontario have recently been taking a new approach to construction, under the guidance of the Ministry of Transportation of Ontario (MTO). As opposed to traditional cast-in-place concrete bridges, the MTO has begun to replace bridges using precast concrete components. This method is intended to reduce construction time and consequently, the amount of time for which the bridge will be out of service. Logistically, precast concrete bridge components must be cast in sections and then constructed on-site, using compatible high performance materials.

This new approach to bridge replacement was utilized to replace a bridge on Highway 24 (Rest Acres Road) in Brantford, Ontario, and used only precast concrete components. Based on the construction timeline, the general contractor, Dufferin Construction, was required to use a material that would reach a compressive strength of 20 MPa within 24 hours, in order to connect the precast concrete abutment sections. Even though the product was not specified by the MTO, Dufferin Construction elected to use KING HP-S10 based on past successes. One such past success was the construction of the Aberdeen Avenue Overpass in Hamilton, Ontario, in 2010.

The concrete pour was completed over two days, as the North and South abutment connections were poured separately. KING provided technical support staff to oversee and assist with the mixing and placing of the HP-S10, during both pours. As test results showed that the placed HP-S10 exceeded the compressive strength requirements of 20 MPa within 24 hours, the contractor was able to continue with construction, on schedule.
