On September 30, 2022, Metrolink and Amtrak suspended train service on the LOSSAN corridor — the nation’s second busiest rail corridor which connects Los Angeles to San Diego — due to erosion under the train tracks in San Clemente. Suspended “indefinitely,” the corridor is used by more than 8 million people annually; freight trains move $1B worth of goods along it each year.
In January, 2019, part of the Arroyo Seco bike path was washed away during a storm, leading to a full closure of the two mile long path that connects Northeast Los Angeles to Pasadena. The bike path didn’t reopen until February 2020, 13 months after the closure.
