It's one of those small details you never notice until you are trying to navigate it by bicycle... The lack of a curb cut at the western junction of Commerce Dr and Freedom Path in Decatur meant that cyclists heading to this side of town either had to exit the path a 1/2 mile early, miss their turn, or jump their bike off a steep curb. This simple, inexpensive upgrade will do a lot for mobility in the corridor.
In the bigger picture, many transportation engineers are still trying to wrap their heads around the difference between a bicycle access point (basically a driveway) and a pedestrian access point which needs ADA accommodations. Not to mention the unique routing that bicycles need to re-enter the roadway correctly from a shared-use path.
