It's been a long, long time since bike lanes for Bloor Street had been first proposed. Just ask Albert Koehl, lawyer and cycling advocate, who detailed the history—first proposed in 1977! (Or Hamish Wilson, who for many years carried the torch despite the "Bloored vision" of City Hall—tip of my hat to Hamish's famous turn of phrases for Caronto).
Lay down a sewer pipe and there are myriad standards dictating dimension, clearance and placement. Lay down a bike lane and sound design precepts are optional, more often recognized in the breach than in the application. How is it that conduits for sh_t are typically subjected to greater planning rigor than conduits for human beings on bicycles?
