Tributary to the North Saskatchewan River

The original structure at this site was greatly undersized which resulted in numerous wash outs and overtopping of the roadway. Additionally, a large amount of drift commonly accumulates at this site. MPA’s design allow for the two pipe structure to be consolidated into a single barrel culvert replacement that adequately passes the design flow. By providing a larger single barrel structure, a concrete end treatment was implemented. This end treatment aids in preventing future washouts and preserves the structure during drift removal.
