Update This location might not be in the city of Englewood, anyone know who's it is in?
Last Friday a cyclist was riding in Englewood in the Denver Tech Center descending a hill. Given that fall is coming on the shadows from the trees are becoming stronger and one tree was shadowing a "speed bump" leaving it nearly invisible to the cyclist resulting in them hitting the pavement at speeds around 20mph and putting them in the ER. Here is the location of the incident Interestingly enough, the city of Englewood on their website does not use speed bumps
Results of various studies have raised concerns about the potential dangers of speed bumps. Speed bumps are not recognized by the State of Colorado as an official traffic control device. Injuries caused by speed bumps may result in significant additional liability for the City. For these reasons, the City of Englewood does not use speed bumps on public streets and alleys.
Here is a second view of the speed bump view too
The final result gave the rider some extreme road rash (they sent me the photos but won't share) and has left their leg immobile for a unknown healing time. So if Englewood does not install speed bumps then who did? It would be assumed that if the city had some street paint might have been added to warn users of the road of this.
