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.
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
