The 21st Street and Yale Avenue intersection was rehabilitated in 2005 as part of a street rehabilitation project on 21st Street between Pittsburgh and Yale avenues. The roadway was resurfaced, and a third westbound lane was added to 21st Street between Yale Avenue and the Expo Square entrance, at which point the lane becomes a right-turn lane. Left- and right-turn signals were converted to the "doghouse" design, which is occurring all over Tulsa. The westbound right-turn lane and arrows were eliminated, as this lane now continues to Expo Square. Right-turn arrows are in place at that intersection. The left-turn medians also were partially removed. In the background, one can see "Zingo" rising above the westbound set of traffic signals. The white water tower is gone. Photo taken July 2005.
