Twenty-First Street and Boulder Drive is the last major intersection in Tulsa to retain the green-arrow configuration that once was at most Tulsa intersections that had left-turn lanes. For intersections that had left-turn lanes on each approach without right-turn lanes, this configuration was used. In most cases, those with right-turn lanes had a three-light signal on the pole with green and yellow arrows and a red light. For those that had left-turn lanes on one or two approaches, the configuration shown here was used minus the yellow right-turn arrow. This intersection is scheduled to undergo a major rebuilding project in conjunction with the 21st Street bridge project, as northbound traffic is very heavy in the a.m. rush hour on Riverside Drive. Presently, the outer lanes on the 21st Street bridge are closed to traffic (occurred in August 1977) due to deterioration. The project includes rehabilitating the river bridge and the intersection and replacing the railroad bridge west of the river, which is scheduled to begin later this summer. All of these projects are funded by 1980 sales tax. A sign of the times, Tulsa Trail, can be seen at right. This "trail" took motorists to the various attractions and points of interest in Tulsa. Previously, the sign was a blue sign with a large "T" that had "ulsa" and "rails" in lowercase letters. Hence, "Tulsa Trails." The warning sign on the bridge approach says "Right lane closed ahead," and a couple of orange barrels that block off the lane can be seen behind the cement truck. In the background is the 21st Street and Riverside Drive intersection. Photo taken June 1982.
