Design Description

Left turn traffic is separated from arterial and cross-street thru and right-turn movements by elevating all left turns to a separate, elevated intersection using narrow ramps within the median. Both the elevated and at-grade intersections are controlled by simple two-phase signal. Left turn traffic descends from the elevated intersection and merges into thru traffic lanes.
