After reading William Trombley's article "The High Road," (Metro, Aug. 14), as a concerned and experienced engineer I would like to offer an interesting, new idea to the double-decking of our freeway. We all agree that improving the capacity of our already overloaded freeways is vital to the survival of our region. We Californians love the freedom that our automobiles provide, and neither the "convenience" of the RTD nor the speed offered by the diamond lanes can tempt us out of our own cars.
I suggest the construction of a reversible three-lane elevated structure for passenger cars only. This offers certain advantages over the presently planned elevated Transitway:
1. Better economy: Since the weight and impact of passenger cars are considerably less than loaded buses, the construction of the three-lane, elevated bridge structure is less costly than a two-directional elevated busway. Similar to express building elevators, this elevated roadway would provide limited access, say, every three to five miles.
2. More traffic: Three lanes could double the capacity of the one-lane, high-occupancy bus lane. The three reversible lanes would augment the capacity of the heavier directional traffic flow of the four-lane roadway by as much as 75%.
