Many freeways around Toronto use concrete and according to the MTO it is cheaper. But the deciding factor appears to be the number of trucks passing the stretch of road. Concretes durability under weight more than offsets the decay from weather.
- jhloa2 7y agoThat's where I notice them as well. I haven't seen it recently, but I recall a few years ago there was a highway around here (Denver) that was asphalt for the two leftmost lanes with a concrete slow lane that semi trucks were supposed to drive on. Maybe Denver is particularly bad for concrete roads because our freeze/thaw cycles get really bad. We have so many warm days in the winter interspersed with cold days and freezing nights.
