The 81st Street and Yale Avenue intersection has become one of Tulsa's worst unimproved intersections for the early 1990s. Traffic jams occur daily, and improvements are not planned until the mid 1990s. A 1991 sales tax project will widen the intersection to six lanes on Yale Avenue and four on 81st Street, with left- and right-turn lanes each direction. To ease congestion in the interim, the city of Tulsa has installed left-turn signals for eastbound and southbound traffic that operate from 4 to 6 p.m. weekdays. Traffic flow has improved when these signals are operational, but congestion returns to the intersection and is routine when the signals are inoperative. Photo taken May 1993.
