Bike Lanes on Indian School??

Why do we have bike lanes on Indian School Road? First, they are dangerous. There should not be bike lanes on major arterials. Second, they are not used. Third, they are not continuous and, therefore, even more dangerous. Finally, even though there is little or no bike traffic on Indian School, either east or west of Central, there IS a tremendous amount of vehicle traffic at that intersection which regularly gets backed up. If you have ever traveled eastbound on Indian School toward Central in the right lane you have probably been irritated by the need to change lanes to the left in order to accommodate the bike lane (even though there are no bikes). When I challenged the Phoenix transportation planners on this and suggested that they might have made a mistake with the plans for this intersection, their comment was “We don’t take out bike lanes once they are installed.” Isn’t it comforting to know that there is a government entity that does not make mistakes?
