Trans-Canada Highway / Stoney Trail Interchange

Abutments generally serve three purposes:

  • Support the bridge superstructure
  • Retain the road embankment
  • Support the end of the approach pavement

Last Thursday night, four pre-cast concrete girders were installed on the south span of the new ramp bridge from southbound Stoney Trail to eastbound Trans-Canada Highway.

Trans-Canada Highway / Valley Ridge Boulevard N.W. Interchange

Controlling water infiltration and providing adequate drainage is critical to the performance of retaining walls and abutments. A trench directly behind the west abutment is lined with filter fabric and filled with porous backfill to support proper drainage.

Proof rolling is a process where a heavy vehicle is driven over a designated area of compacted soil to check for soft, yielding, unstable, loose, wet or otherwise unsuitable foundation conditions.
