    $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.
