Green Line - Construction

78 Avenue S.E. Road Widening and Underpass Project

The City is doing several construction projects, called Enabling Works, to get ready for the Green Line LRT. One of those projects is the 78 Avenue S.E. Road Widening and Underpass Project.

Project highlights:

  • initial utility work to prepare for construction,
  • building an underpass to connect 78 Avenue S.E. under the CP tracks to Ogden Dale Road;
  • road construction on 78 Avenue S.E.; and
  • closing 69 Avenue S.E. at the CP rail crossing.
Completing this project now will help us when it comes time for us to begin construction of the Green Line LRT in 2020.
