As 2017 gets underway, there are at least 23 protected bikeways in the Washington region, totaling over 9 miles. This map shows them all.

Or at least, all those I know about. There are so many now that it's becoming hard to keep track. 

The 23 bikeways range from lengthy to minuscule. DC's 15th Street cycletrack is both the oldest in the region and, at about 1.6 miles, the longest. On the other end of the spectrum are microscopic sections of normal unprotected bike lane where a few plastic bollards add a tiny degree of separation for a short stretch. The smallest is at the corner of New Hampshire Avenue and U Street, where a mere 60 feet of lane is protected with curb and flexposts.

The District has by far the most mileage of protected bikeway, with about 7 miles and all of the five longest individual bike lanes. After DC, Arlington and Montgomery are in a virtual dead heat for second place, each hovering with almost exactly one mile of protected bikeway, spread across four separate locations in each county.

Prince George's, Alexandria, and Fairfax City each have tiny cycletracks, combining for one-quarter mile. 

For the future, DC has grand plans for a vast cycletrack network, and more jurisdictions are beginning to work on their own. Expect this map to expand in coming years. 

In the meantime, if you know of an existing protected bikeway that's not on this map, leave a comment to let us know. 

Update: This post has been updated to reflect additional protected bikeway segments that were missing from the original map.
