How much does 60km of two lane road cost for comparison? I would think building a bike path would end up being cheaper.

Also lifetime maintenance....

Bikes cause hardly any damage vs cars making potholes every year

Way more. I'm working on a road project now. Asphalt for a road (100mm thick) is being bid at approximately $35/sq.m. Granular are about an extra $30/sq.m.

For a standard residential size road (8.5m curb to curb) that puts you at $552/m of road length, or 33mil. The big costs on top of that number always come when you've got to remove the old asphalt and gravel ($75/cu.m), as well as all the fiddly little stuff like line painting, tying in grades to make sure you have drainage, sod restoration, tree plantings, etc.

$1-3m / km. So 60 km of 2 lane road would cost $60-180 million. Probably on the higher end for Montréal being an urban area.

But roads can cost as over $5Bn for 1.7km (looking at you Gardener Expressway). So $2,941 million /km for however many lanes that is.

These bike lane in particular are probably more expensive than brand new lanes, as they also require road adjustments.

Bikes don't cause potholes, so maintenance is cheaper.

[-] Nouveau_Burnswick@lemmy.world 3 points 1 year ago

Yeah, those are just construction costs.

Road maintenance bills are quite high.

A bike path only needs SNIC and a rebuild after 30 years.
