"Last fall, the government announced plans to replace the eastbound bridge, widen the westbound bridge and build a new, stand-alone pedestrian bridge over the Bow River in southeast Calgary.

The project will boost the number of lanes to four in each direction — currently the eastbound crossing has two lanes, while the westbound has three." https://www.cbc.ca/news/canada/calgary/pcl-construction-stoney-trail-bridge-calgary-bow-river-contract-1.5866403   Jan 08, 2021
