Officials say for the first time during a 17-year study of mountain lions, one of the big cats has been documented crossing Interstate 405 in Los Angeles.
The National Park Service said Thursday that P-61 navigated the massive freeway between 2 a.m. and 4 a.m. on July 19 in Sepulveda Pass.
The NPS called it a rare feat.
In the same area where P-61 crossed, a mountain lion dubbed P-18 was hit and killed by a vehicle in 2011. A lion not tracked by scientists was killed along the stretch in 2009.
The most famous big cat to cross the 405 is P-22, a lion that lives in Griffith Park. P-22 was not collared at the time, so little is known about his journey.
