Here is yet another real world example of how bicycle access (in a cold climate city) improved the local business climate.
NYC DOT found that protected bikeways had a significant positive impact on local business strength. After the construction of a protected bicycle lane on 9th Avenue, local businesses saw a 49% increase in retail sales. In comparison, local businesses throughout Manhattan only saw a 3% increase in retail sales.
I love complete streets and will fight for them.
