"You should know that bicycling improvement construction costs run about $70,000 a mile; for 12-foot shared paths about $128,000 a mile; 5-foot bicycle lanes about $189,000 a mile; 5-foot paved shoulders on rural roads about $102,000 a mile. You should also know that one mile of urban freeway costs on average $46 million a mile. Don't let anyone tell you we can't afford bicycle lanes! You know better".
