NEAHD:

The North East phase of the Anthony Henday Drive connects the North East corner with the loop around the South side of Edmonton with a series of overpasses and roadway spanning 18 km. Over the past 100 years of farming and industry, the pipeline companies have taken over a fair chunk of the realestate along the Yellowhead and Baseline Road on the East side of the city. In planning the 17 new structures in the area, special consideration was required to appease the pipeline companies regarding the increased loading of the roadway crossings and consider the horizontal alignments in the foundation designs. We made almost 200 holes along the route to identify pipelines and major utility conflicts up to 6m deep. Special consideration was required to provide rig-mats for access across the pipeline corridors, coordinate traffic control with Alberta Highways and manage the weather as all of the excavations were completed in the dead of winter. The follow up on this job included a spring visit to clean up all of the holes, top them up with sand and drop some grass seed on the top, so the dozers and graders had a pretty place to park before they tore up the ditches for as far as you can see.
