National Trails Highway Bridges 113 and 130 Emergency Activities (Nov 2026)

Recent storm events in the desert areas have caused concentrated runoff, debris movement, sediment deposition, and severe erosion at Bridges 113 and 130 along National Trails Highway. These storm-related impacts created cavities and undermined bridge wing walls, abutments, channel slopes, bridge piles, fascia, and curbs. Both bridges are currently closed because the damage presents an immediate threat to structural stability, public safety, and transportation access. Work includes but is not limited to, removing storm-deposited and unstable material, restore channel capacity, stabilize erosion cavities and bridge foundations, repair erosions and slopes; repair damaged wing walls, abutments, fascia, curbs, and other appurtenant structures using in-kind material. The work must be completed before additional El Nirio storms to prevent further erosion, undermining, structural damage, and potential bridge failure.
