État du pont Pie-IX, ou du moins ce qu'il en reste!

By the time the Blue line extension is complete, the tunnel will be due for refurbishment.

Aux environs de Beaubien et Bellechasse.

I still don’t think the pavement they chose is sufficiently distinguishable from regular driving lanes. What is it with road paint in this province?

You cannot rely on road paint if it is partly hidden by snow 2-3 months per year.  Same goes for parking limitations for which we we use pole-mounted signs on the street.

Once again, the idea that snow somehow limits the use of more vibrant colours appears to be yet another local assumption. How do other snow-belt cities — none of which come close to having the snow removal capabilities and expertise of Montreal! — manage to use properly distinguishable pavement colours for transitways and bike lanes? Why must we always aim to do things differently from established norms, and inevitably fail to do things better than the how it’s done elsewhere?

Minneapolis, which has hotter summers, colder winters, and more storms than Montreal:

Boston (more snow per snowfall, lousier clearing):

Toronto, New York, etc. all use red paint or MMA. But even places that use pigmented asphalt have more contrast than we use. Pigmented asphalt costs substantially more than paint, thermoplastic, or MMA, and is less flexible — ie more costly to repair or do over — so it’s not a question of costs.

Les amaricains sont parfait, ils l'ont l'affaire eux autres, voila quelques exemple éloquent a Minneapolis la parfaite

nous les québécois on est trop simplet pour comprendre le concept de la peinture sur les routes. 

petite stat sur les accumulation de neige pour finir (2019)

Minneapolis : 137 cm

Boston : 111 cm

New York : 63 cm

Toronto : 152 cm

Montreal : 235 cm

p.s: the claim about colder temps in Minneapolis are completely false, we have the same averages.

That doesn’t change the fact that we, in Montreal, spend more than double the next closest city on snow clearing, and we are indisputably the best at snow clearing anywhere in the world. The point wasn’t about the paint coming off, it’s about how we “cannot rely on road paint if it is partly hidden by snow 2-3 months per year.” We clear the snow, the notion of not using brighter-coloured road markings because they’d be “hidden” by snow is nonsense if other cities that get snow (and don’t clear it as well as we do) still manage to use contrasting colours for transitways and bike lanes. We also don’t repaint road markings anywhere nearly as often as other cities do.

Faudrait effacer les images dans l'entête du fil si on ne peinture pas les routes...
