Concrete islands, curb extensions and so-called “bump-outs” are often installed on Chicago streets in an effort to slow traffic, shorten pedestrian crossings or organize parking and traffic lanes. When properly designed and clearly marked, these improvements may serve an important safety purpose.
But when a concrete bump-out suddenly extends into the path of a bicyclist or e-scooter rider, particularly when it is difficult to see , the supposed safety improvement can itself become a serious hazard.
A recent tragic e-scooter death in Chicago demonstrates just how serious this problem can be.
