Big R completes first Super•Cor rail underpass in US

A recent Indiana Rail Road project marks a milestone for Big R’s rail team. Although our structural plate products are used for many demanding applications worldwide, this was the first rail underpass built in the US using Super•Cor Structural Steel Plate.

Super•Cor trumps concrete on time, cost and performance

For decades, concrete has been the rail sector’s product of choice, but cost-effective Super•Cor was chosen over a 175' five-span concrete bridge due to the significant savings it represented. Unlike concrete alternatives, Super•Cor doesn’t require specific weather conditions, specialized contractors and equipment, or additional curing time. Plus, very little maintenance is required over the life cycle of the structure.

As the lead rail line into Bear Run Coal, an extended closure was out of the question. We recommended a Super•Cor Arch with our Vist-A-Wall MSE Structural Walls (Wire Walls) for the headwalls and wingwalls. The use of Vist-A-Walls under rail was another US first.

A Big R solution for every challenge

Short timelines, harsh weather, weak soil foundations and a tight right of way made this project particularly challenging. The under rail structure was value-engineered with increased height to reach better foundation material and eliminate the need for deep piles. Big R was also able to respond quickly with on-site assistance and revised drawings when grade conditions changed. All of this leading to a favorable response from the client at the end of the project.
