The cost of a five-foot bicycle lane can range from approximately $ 5,000 to $ 535,000 per mile, with an average cost around $ 130,000. The costs can vary greatly due to differences in project specifications and the scale and length of the treatment. For this reason it is of vital importance to know the cost of the bike lane, because being a busy road the cost could rise.
