The flooding has severely impacted transportation and wastewater infrastructure in the Four Corners region, spanning Colorado, Arizona, New Mexico, and Utah. In Colorado, roads such as US 160 and CO 151 have suffered significant damage, including culvert failures, sinkholes, and collapsed sections. La Plata County has closed all county roads, and Pagosa Springs faces restricted access due to road washouts. In Arizona, state highways near Sedona were closed, while New Mexico and Utah reported damage to water and wastewater systems, roads, and bridges. Recovery costs in New Mexico alone are estimated to reach $200-300 million.
