A man who was threatening to jump from the 43rd Street overpass of Interstate 805 prompted officials to close the freeway Friday and call in emergency negotiators.
All lanes were reported open at 2:38 p.m., the California Highway Patrol (CHP) reported.
The man was spotted sitting on the overpass with his feet dangling around 7:45 a.m. and the San Diego Police Department's emergency negotiating team was brought in, according to San Diego police Officer Frank Cali.
Police took the man into custody shortly after 2 p.m. and turned him over to CHP officers, Cali said. It is not known if the man will be taken to the county's Mental Health Services for an evaluation or face charges, Cali said.
The CHP issued a SigAlert at 8:39 a.m. for the northbound Interstate 805 lanes. The on-ramps from Plaza Boulevard and Sweetwater Road in National City were shut down.
Northbound traffic was being diverted to eastbound and westbound state Route 54, then back onto the interstate, according to the CHP.
The southbound lanes were also closed and traffic was being diverted onto state Route 94, according to Caltrans. Motorists were advised to avoid the area.
