Super-Cor Arch, MSE Wire Walls provide quick temporary crossing for Toronto’s Metrolinx construction

December 2, 2025

As part of the Metrolinx LRT expansion in Toronto, a temporary crossing was needed for construction vehicles to cross a series of high-voltage utility lines near the Leaside Bridge in the Don Valley. This was an urgent request because construction of major pile works for the elevated LRT line had been stalled over the issue.

We proposed an uncoated (black steel) Super-Cor Arch on precast concrete footings with MSE Wire Walls with fabric at the face. The order was given to us on the condition that we deliver material and IFC drawings within a four-week window.

Here’s how we made in happen
Because of the short timeline, we worked with conceptual designs to start manufacturing and had the fabrication prioritized. The contractor, Leaside Builders, was pleased when our manufactured product and the IFC drawings were all delivered on time.

During site visits, we were able to review some construction challenges and provide valuable insights to help keep things moving.

  • Pre-assembled Bolt-A-Plate Arch with precast concrete footings and headwalls accelerates late-fall BC installation

    This November 2022 project in Grindrod, BC, was an interesting one as the headwalls and footings were prefabricated off-site to allow for a faster installation — which was required to get it completed before winter took hold.

  • Flexible thinking helps extend existing Super-Cor Box Culvert

    A private road-widening project in Vernon, BC, highlighted our capabilities in tackling complex projects. Connecting a new Super-Cor Box Culvert to an existing one (designed in 2000) was challenging due to weak foundation soils and a zero differential settlement requirement at the connection. Also, precisely matching their shapes can be complicated once the plate is assembled.

  • Tight site calls for two-stage construction

    The Route 1 Gateway Project, is a major DOT highway upgrade across southern New Brunswick to the US border. AIL is pleased to have partnered with Dexter Construction to deliver five engineered plate structures. One particular Super-Cor Arch stream/wildlife crossing presented particular challenges.
