ST. LOUIS – Interstate 44 was shut down for three hours Wednesday afternoon and evening because of a police investigation at the Jameison overpass.

According to Evita Caldwell, a spokeswoman for the St. Louis Metropolitan Police Department, the incident happened around 4:45 p.m. Police received reports of an individual running back and forth on the interstate at Jamieson.

Police found the person, a 38-year-old man, had scaled the girders and climbed onto the overpass.

City police and firefighters, as well as EMS and members of the St. Louis Street Department, responded and tried to coax the man down. The man was eventually taken into custody and brought to an area hospital for a mental evaluation.

No injuries were reported, Caldwell said.

The man interacted with an employee at a nearby gas station before climbing onto the overpass. He turned off the fuel pumps at the station by hitting the emergency shut off valve.

The delays on the interstate lasted for hours. Some drivers had trouble keeping their cars running for that long. The gas station worker claimed that some drivers were running out of gas.
