Northeast Stoney Trail (NEST) is a 21 km section of Calgary’s which extends from , south to 17th Avenue SE.

Northeast Stoney Trail

In addition, the construction schedule ran through the winter months, where temperatures can plummet below -30˚C. Acute angles (i.e. 34.3˚) added an additional level of geometric complexity to the design process, not typically seen in MSE wall design.

Solution To accommodate the size and construction challenges, Nilex recommended the ARES System, a full-height pre-cast system for the bridge retaining walls, in conjunction with the innovative use of HDPE soil reinforcement. The pre-cast panels allow for custom textural and pattern designs to fit the architectural and The Nilex Advantage budgetary needs of the project.
