4.8.6 Option 3
Option 3 (Figure 4-14) improves mobility along the corridor by creating a continuous
five-lane cross section without raised medians. The center lane consists of exclusive
left-turn lanes at the signalized intersections and a two-way center turn lane
(TWCTL) for the remainder of the corridor. The TWCTL lane helps remove leftturning
vehicles from the through lanes, thereby reducing congestion and rear-end
crashes. Construction of the center lane requires minor roadway widening because
shoulders and sidewalks are still provided on both sides of the road. The
intersections are controlled by traffic signals, similar to Option 2.
