The Angeles Crest Highway, a 66-mile scenic route through the San Gabriel Mountains, remains closed indefinitely following severe weather damage that has left the roadway in a state of disrepair. The highway, which connects La Cañada Flintridge to Wrightwood, is currently impassable from 3.3 miles east of Newcomb’s Ranch to State Route 138.
The closure follows a damaging atmospheric river event last December that brought more than 10 inches of rain to parts of the San Gabriel Mountains over 48 hours. This extreme weather caused landslides, rockfalls, and significant erosion, resulting in the destruction of multiple sections of the road.
Repair Efforts and Current Status
The California Department of Transportation (Caltrans) is currently managing three emergency repair projects along the route. Crews have identified approximately 40 locations requiring attention, though officials note that this number could increase as further assessments are conducted. Repairs include installing K-rail barriers, reconstructing eroded slopes, and installing temporary traffic signals to manage one-way traffic in restricted areas.
For those navigating the area on foot or by bicycle, the highway presents a stark landscape of construction and natural damage. Excavators are actively working to restore drainage areas where water flow has carved away sections of the pavement. Hikers and cyclists are advised to remain cautious, respect the instructions of construction crews, and prepare for significant debris and unstable terrain, particularly near creek crossings.
Looking Ahead
There is currently no established timeline for the reopening of the highway. Because the damage is widespread and involves multiple structural failures, the road may face extended periods of closure. The situation mirrors challenges seen on other major California routes, where extreme weather events are increasingly common, leading to a cycle of damage and repair that may redefine access to backcountry areas in the future.
