North by northwest
The addition of a north line to Edmonton's growing light rail transit (LRT) system—the Metro Line—is an important project to accommodate Edmonton's growing population. It is also the winner of an Alberta Construction Magazine Top Projects Award in the Civil—Over $50 Million category.
The 3.3-kilometre line runs from the Churchill LRT Station northwest to the Northern Alberta Institute of Technology, North by northwest with stations added at MacEwan University and Kingsway/Royal Alexandra Hospital. About a kilometre of the line is underground and was completed using what is called Sequential Excavation Method tunnelling. Other highlights of the project include:
→ A tree canopy used along 105 Street between 107 Street and 108 Avenue saved and protected decades-old elm trees along both sides of the street.
→ The connection to the existing LRT line involved a six-switch, three-diamond connection constructed inside an
existing underground cavity in two phases alongside live LRT operations in less than four months.
→ A short-term-pain-for-long-term-gain approach was used for pedestrian and vehicle traffic, resulting in shorter
impacts to the public.
→ The complexity of building two kilometres of a light rail system through city and residential communities.
Once the new line goes into service next year, the city expects weekday ridership to increase by 13,200. That number will grow even more when the Metro Line expands into St. Albert, though no firm timetable has yet been set for that.
