Streetfilms has put together this video to explain the 200+ miles of new bikes lanes that New York City has installed over the past few years.  Over the three years they were put in place, bicycle traffic has increased 45%, and NYC is well on their way to meeting their goal of 1,800 miles of bike lanes by 2030.
The NYC DOT has put in place three different types of lanes depending on the road type and width, including some left-side lanes to help prevent cyclists from getting doored.  Even if you don’t live in NYC, it’s worth watching to see what can be done when you can widen the roads…a perfect lesson for any city.  If NYC can do it, it can be done pretty much anywhere.
