Please note: I’ve posted an updated version of this animation that is much more detailed.

infrastructure, circa 1980. See how it has evolved below.
Portland’s bike network was not built overnight. Most of our bike-specific infrastructure was built in the mid to late 1990s, but it really started in the early ’80s. About seven years ago (before many of you even knew about BikePortland), I stitched together an animation showing how Portland’s bike network has evolved.
Yesterday, something on Twitter sparked my memory of the animation, so I shared it again. Given how it has spread overnight, I figured many folks might be interested in seeing it again (or for the first time). The animation shows the spread of bike-specific infrastructure in Portland from 1980 through 2005 (and then into the future) in five year increments. Check it out:

This really puts what has happened here into perspective don’t you think?
And by the way, the graphics are taken from a presentation given by City of Portland Bicycle Coordinator Roger Geller. Thanks Roger!
