Description:
Title 23, U.S.C., Section 125, authorizes an Emergency Relief (ER) program within the U.S. Department of Transportation, Federal Highway Administration, for the repair or reconstruction of Federal-aid highways and roads on Federal lands that have suffered serious damage as a result of natural disasters or catastrophic failures from an external cause. These funds are awarded to a State after the President or the Governor issues a formal emergency declaration and the State files a request for ER for the cost of damages to its eligible highways. Eligible repair work includes emergency repairs needed to restore essential traffic, minimize the extent of damage, or protect the remaining facilities as well as permanent repairs necessary to restore the highway to its pre-disaster condition.


Between June 26, 2021 and July 28, 2021, I-70 within Glenwood Canyon in Colorado was closed twelve times while a flash flood warning was sounded. At least five of these warnings resulted in mudslides and debris flows that extended the closure for an additional 12 to 36 hours to allow Colorado DOT staff to clean up the road. The debris flow locations number in the dozens throughout Glenwood Canyon. On Thursday, July 29, 2021, a major rainfall event dropped between 2 and 4 inches of rain in about an hour throughout the Canyon. This event caused most of the debris paths to activate and, with the intensity of the rain, the debris flows were more intense than had previously been experienced. A similar rainfall event occurred overnight between Saturday, July 31, 2021 and Sunday, August 1, 2021. I-70 has been closed since the first of these two major storm events on July 29, 2021. The slides that closed the road earlier in July inundated the facility with mud but did only moderate damage to the infrastructure. The storms of July 29, 2021 and August 1, 2021 caused considerable damage to at least four discrete structures in the Canyon and possibly more that will be known when the debris is removed from the affected areas. To date, Colorado DOT has observed damage to prestressed overhanging superstructures, retaining walls along the Colorado River, various damage to decking, several sections of guardrails torn away, and numerous drains damaged.
