That’s actually a good argument behind both widening I-70 and funding part of that construction with tolls. The tolls, especially if they’re higher for periods of high traffic, would discourage some of the “invaders” from coming, and part of the proceeds could fund a wrecker service to clean up accidents more quickly.
I live near Glenwood. The canyon is never going to be widened. It was hard enough to build it in the first place. There is not enough capacity through town either, and no good way to fix the problem.
