A crane moving concrete barriers on a South Park freeway ramp toppled over early Wednesday, seriously injuring a laborer and leaving traffic lanes in the area blocked for hours.
The accident on the connector between southbound Interstate 15 and westbound SR-94 occurred shortly before 1 a.m., according to the California Highway Patrol and the San Diego Fire-Rescue Department.
The victim wound up pinned between two safety barricades known as K-rails, SDFRD Capt. Joe Amador said. Co-workers were able to free the man prior to the arrival of emergency crews.
Medics took the worker to Scripps Mercy Hospital in Hillcrest for treatment of a severe leg injury.
A second crane was brought in to right the one that had fallen, Amador said.
All lanes were open again at the accident site by shortly before 6 a.m., the CHP reported.
The cause of the crane collapse is under investigation.
