It’s sort of an infrastructure triple junction. Below, you’ve got a big open concrete channel that substitutes for what used to be arroyos carrying water off of what is now a city. Adjacent to it, you’ve got a buried water main, carrying drinking water to the residents of that city. Above it, you have one of the city’s main automobile arterials – importantly, one of the few big streets that cross the Rio Grande.
Water main breaks, undermining street. Hilarity ensues.
