A Houston transportation engineer envisions an ambitious plan for ten miles of underground highway.
Gonzalo Camacho, a 41-year-old transportation engineer in Houston, thinks he can bury the problems of I-45 once and for all - literally. "Sinking a portion of I-45 into a tunnel eliminates the need for more right-of-way, the primary fear of frontline homeowners. A tunnel could be constructed faster than a typical highway and more cheaply than a depressed or stacked system -- though a traditional flatland expressway is still the cheapest. Eliminating on- and off-ramps would make driving safer. And air treatment would help clean the skies by removing up to 90 percent of the solids in tunnel exhaust."
