Excellent to have some calculated numbers!

Two thoughts:

1) Possibly the road could be rearranged to allow travel only in one direction, freeing up at least 1 extra lane?

2) It might be possible to get some of the bigger 50 or 80 capacity transit buses, or some large school buses? One article I found suggested California had in excess of 20,000 school buses, although I'm still looking for a reliable source to back that up.
