Several months after the Station Fire and closer to La Canada Flintridge, heavy rains during mid-January caused several landslides and road washouts along the winding Angeles Crest Highway.
Portions of the asphalt along with fill under the road washed away leaving large gaps in the roadway. A Caltrans damage assessment team determined the most significant road washouts ranged between 50 to 110 feet along the highway and about 200 feet below it at some locations, making the highway unsafe and impassable, Caltrans officials said.
Repair crews are trying slope stabilization by compacting loose dirt and rock, reinstalling drainage culverts below the highway, and reconstructing the roadway, according to Caltrans.
The Angeles Forest (N3) Highway, Big Tujunga Canyon Road and Upper Big Tujunga Canyon Road, which all intersect the Angeles Crest (2) Highway, are open to the public – but delays should be expected on these roads due to other erosion-related repairs and construction, according to Caltrans.
In addition, the Angeles Forest Highway is gated at its junction with the Angeles Crest Highway, due to the Caltrans closure of the Angeles Crest in that area, Caltrans said.
