Earlier Friday, a man threatened to jump from the 43rd Street overpass of Interstate 805, prompting a nearly six-hour closure of some freeway's lanes before he was taken into custody.

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 California Highway Patrol officers, Cali said. It was unclear if he would be taken to the county's Mental Health Services for an evaluation, or would face charges.

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 diverted to eastbound and westbound state Route 54, then back onto the interstate, according to the CHP.

The southbound lanes and a connector from state Route 15 were closed later and traffic was diverted onto state Route 94, according to Caltrans.

All lanes were reported open at 2:38 p.m., the CHP reported.
