The statement from Metro:

A construction worker on the I-405 Sepulveda Pass Improvements Project was killed about 2:30 this morning when a steel construction beam fell on him. The accident occurred on the Santa Monica Boulevard off-ramp from the southbound 405. The worker was pronounced dead at the scene.

Metro expresses its deepest condolences to the worker’s family, friends and co-workers. It is the first serious incident on the I-405 project in nearly three years of work. Further work on the entire project has been stopped while the contractor does a thorough safety review. The incident is being investigated by CalOSHA.
