Wolf Creek

Before Replacement

After Replacement

The previous bridge at this location had reached the end of its service life, was hydraulically inadequate and required replacement.  MPA completed the bridge planning and geometric design for the new bridge structure and 600 m of gradeline revisions to tie into the new deck height which increased by 3 m over the old structure.  MPA’s structural sub-consultant (DIALOG) completed the structural design for the complicated 45 degree skew and semi-integral abutments.

Wolf Creek is a class “A” watercourse with a lengthy in-stream restricted activity period and securing environmental permits and an appropriate in-stream work window proved challenging.  In addition, negotiations with landowners proved difficult but MPA secured the necessary right-of-way to allow the project to proceed.
