Man does a backflip off a freeway sign and onto a airbag

A man climbed atop a freeway sign in downtown Los Angeles, which led to a temporary shutdown of the southbound 110 Freeway Wednesday morning.

The man, who appeared to be only in his underwear, scaled the sign near the Beaudry Avenue exit around 8 a.m. He appeared to hang posters off the ledge of the freeway sign.

California Highway Patrol officers said they were not sure what the man was protesting, if anything. One sign read, “Fight pollution, not each other.”

Police officers and firefighters were on scene. Traffic was backed up for miles.

Emergency personnel scaled the freeway sign and tried to talk to the man to convince him to come down. At around 10 a.m., he eventually did come down – doing a back flip onto the yellow inflatable air cushions deployed by authorities across freeway lanes.

He was placed into an ambulance.

California Highway Patrol officials tweeted at about 10:30 a.m. all lanes are back open.
