Super-Cor Box Culvert with Best-Kote Buried Bridge Coating provides +75-year solution for Quebec municipality

September 15, 2023

Sainte-Sophie-de-Lévrard is a municipality on the south side of the St. Lawrence River between Trois-Rivières and Québec City. To restore access to a regional road, Rang St-Antoine Ouest, the Municipality contracted the engineering consulting firm, Tetra Tech, to conduct a study and recommend the optimum solution.

Tetra Tech recommended a low-rise structural steel product, and an AIL Super-Cor Box Culvert with Best-Kote Buried Bridge Coating was selected.

The new crossing was built adjacent to the existing stream bed with a full concrete invert and pedestals, as recommended by Tetra Tech. Close collaboration with the AIL Engineering team led to some variation and optimization of the foundation elements. Before the onset of winter, Excavations Tourigny completed the project to the satisfaction of all parties.

Box culverts ​offer increased clearance and flow
Super-Cor box culverts offer optimal clearance boxes and hydraulic flow geometry along with shallow covers for low-rise applications.

Super strong, flexible and resilient buried arch bridges
Buried arch bridges, tunnels and other structures made from Super-Cor carry loads through soil-structure interaction, meaning the bridge and the backfill soils act together to support the loads. Settlement tolerances for buried arch bridges are much higher than that of buried concrete bridges. Discover the many benefits of Buried Metal Bridges >>

  • Thunder Bay chooses Super-Cor Box Culvert with Best-Kote

    When the City of Thunder Bay, Ontario, needed to replace an aging closed-bottom culvert under Briarwood Drive, they opted for a Super-Cor Box Culvert with Best-Kote Polymer Coating so they could benefit from its 75+ years of design service life expectancy.

  • Custom Super-Cor Box Culvert bumps concrete alternative and saves Ontario town 20%

    The Town of Essex, Ontario, originally tendered this replacement project a year earlier, specified as a concrete box. However, the project did not make it past Town Council due to its cost. AIL was subsequently contacted by the Town’s consulting engineer to see what we could offer as an alternative. We had an initial meeting and quickly came back with a custom geometry that met their unique hydraulic capacity and height of cover requirements.

  • Eastern Ontario township chooses Super-Cor for the sixth time

    The Township of North Glengarry – about halfway between Ottawa and Montreal on Highway 417 – is now home to its sixth AIL Super•Cor project in recent years. It seems they like working with a proven project partner with efficient engineered solutions like Super-Cor – lightweight, strong and easy to ship and install in rural locations with local crews.
