New York City has seen huge bicycling-related improvements in recent years as a result of Janette Sadik-Khan, former commissioner of the New York City Department of Transportation. In just 6 years, she built out 350+ miles of bike lanes across the city using the simplest tool you can imagine: paint. By painting bike lanes and pedestrian plazas, Janette rerouted the city’s traffic and drove up the retail value of storefronts in all of the reimagined spaces. During her administration, Citi Bike was also launched and now has 12,000 bikes throughout 330 stations across the city, as well as in New Jersey!
