Even when the City tries to do right (let's ignore for the moment where the City does wrong - as with the Jarvis bike lanes removal), little stubborn facts show the City (except for the tiny Cycling Unit in the Transportation Services aka Department of Motor Vehicles) still isn't taking traffic safety seriously.
With the ongoing construction of Strachan for a new overpass to accommodate more frequent GO Transit service, a temporary bypass road was constructed, complete with bike lanes and sidewalks. Mostly. I recorded myself taking the bike lane. The bike lanes are quite nice, but quite inconveniently disappear completely and without warning at the most critical points, where the road narrows and curves. And, like in the video, the bike lane can disappear right next to a large truck, forcing the person to figure out how to avoid being crushed.
Neither cyclists nor drivers are given any warning nor direction on how to act or merge. It appears that no thought was given by planners or contractors on how cyclists are supposed to behave just outside of the reconstructed road. They may have followed the plan to the letter, but somehow someone didn't think to see how the reconstructed bike lanes would meet up with the existing ones.
If the City truly had a plan for improving the safety of cyclists -- if it considered bike lanes an important aspect of increasing safety (and there is more and more research that this is true) -- then they probably would not have created this mess on Strachan. But as it stands it's a symbol of how bike lanes tend to be seen as just gimmicks.
