Taber to Burdett

Study parameters

The study sought to identify staged options to:

  • upgrade the existing 4-lane urban divided and 2-lane undivided highway to a twinned freeway corridor
  • identify access management via an estimated 5 interchange locations

The existing twinned segment through the Town of Taber and the undivided segment through the Hamlet of Grassy Lake may need to be realigned with bypass routes around Taber and Grassy Lake to conform with National Highways System standards.

Executive summary

West of Burdett to West of Taber


The study was completed in Fall 2019.
