All the bridges were being submerged and washed out by rapid amount of water riding.

The overflow that had came down was uncontrollable for the city of Los Angeles and continued to destroy many aspects as the rainfall continued until 7 p.m.(Liquid) March 3rd. Although the rainfall stopped, the mountains continued submerging the city of Los Angeles under inches of rain into the Santa Ana rivers and caused it to continuously rise and putting many citizens and victims in danger.
