Bidirectional protected bike lanes, which put both directions of bike traffic on the same side of a street, aren’t ideal. But they can be useful in a pinch.
Like all protected bike lanes, well-designed bidirectionals are more comfortable to more riders than having no bike lanes on busy streets.
This month in downtown Atlanta, something interesting is happening for the first time in the United States: two bidirectional protected bike lanes are crossing each other at a four-way intersection.
Fortunately, both of them are on the “left” side of signalized one-way streets. This is generally the best way to use a bidirectional protected bike lane, in part because it prevents total chaos in situations like this one.
