I don't want to belabour the point because I fundamentally agree with all of the critiques of Calgary's cycling infrastructure. The only thing I want to dispute is the idea that the Calgary guy is taking the best available route. In fact, he claims that there's no alternative to Macleod. A simple Google Map query pulls up several alternatives that are actually shorter, make better use of the pathway system, and avoid Macleod.
Look, I hate Macleod as much as everyone else. If I was emperor for a year, I'd completely redesign Macleod north of Glenmore, reducing it from 7 to 4 lanes (2 lanes, if I was feeling extra ambitious). Cars on Macleod south of Glenmore can be diverted along the Glenmore to Deerfoot, Blackfoot, or Crowchild, leaving Macleod to be an urban boulevard. That would also allow us to convert Macleod and 1 st SE into two-way streets throughout downtown and the Beltline. In fact, Macleod could actually be pedestrianized between Olympic plaza and City Hall, creating a much larger, continuous civic plaza.
