By 12:20 p.m., authorities confirmed that the man was brought down safely from his precarious position on the walkway and the freeway lanes were reopened.
The incident initially shut down four southbound lanes of the 170 Freeway between Sherman Way and Victory Boulevard, authorities said.
Firefighters set up an airbag underneath the walkway, which is located just south of the Sherman Way exit. Los Angeles police officers spoke with the man at length before convincing him to come down.
The man was taken for a mental evaluation, authorities said.
