Also significantly less. The reason road needed to repair is usually caused by ground erosion(which will happened regardless), tree root damage(which will also happened regardless), and the vehicle(plus speed) moving above. The heavier the vehicle using it, the quicker the road will be damaged. The weight of a sedan + driver is usually 10 times or more heavier than bicycle + rider, and the speed of a car on the road is usually 3 to 4 times of the bike. Unless the bikelane is build on top of ground that is prone to movement or near a big tree, it will last way longer than the road build solely for car.
Maybe I wasn’t clear. I meant the maintenance cost for the road (and the bike, but I suspect the road is the bigger cost). Clarified in the original.

Good point, thanks
