Crowchild Trail typically sees 100,000 vehicles or more every day.
City transportation engineer and project manager Jeff Baird said rehabilitating and expanding Crowchild Trail over the Bow River was a complex task that involved building a separate bridge underneath to do repair work while keeping lanes open for traffic above.
Lanes have been kept open in both directions on the bridge between 5 a.m. and 9 p.m. on weekdays despite construction.
“Any time you’re working with decades-old infrastructure like this, let alone multiple bridges, there’s challenges,” Baird said.
“In addition to the river, the project had to account for busy roadways, busy pathways, two sets of train tracks and sensitive habitats beneath, all while keeping the 100,000-plus vehicles a day that travel through the area moving.”
Baird said as construction winds down, Calgarians might still see crews doing finishing touches such as landscaping and cleanup.
That will mean periodic lane closures, he said, but “nothing close to what we’ve seen” during the height of project work.
In 2017, city council approved recommendations from a study on how to improve Crowchild Trail between 17th Avenue S.W. and 24th Avenue N.W.
That came after earlier plans to overhaul Crowchild Trail were thrown out in 2012 over concerns that parts of several neighbourhoods would be bulldozed in the process.
Nenshi said Tuesday that was an “old-fashioned plan” and the city is on a better path after extensive engagement with affected communities.
