CTA trolley bus 9577 has the poles down in this June 1970 photo. Although signed for Route 72 – North Avenue, I have to wonder if the actual location is a wye located at Central Avenue and West End Avenue. This was an unusual arrangement where a bus would go head in, then back out to change direction. (Charles L. Tauscher Photo)
