DC has had a smattering of bike lanes since at least 1980, but the network only started to grow seriously starting in about 2002. This animation shows the growth of DC’s bike lane network, from 1980 through to 2012.

From 1980 to 2001, literally nothing changed. Then in 2001, two short new bike lanes popped up. The next year there were 5 new ones. From then on, District workers added several new bike lanes each year, making a boom that’s still going on.

This animation ends in 2012, so it doesn’t include recent additions like the M Street cycletrack. But it’s still a fascinating look at how quickly things can change once officials decide to embrace an idea.

In a few years, a map showing the rise of protected bike lanes might start to look similar. That map would start in 2009 with DDOT’s installation of the original 15th Street cycletrack. It would expand slowly through this decade, then maybe (hopefully), it would boom as moveDC’s 70 mile cycletrack network becomes a reality.
