During the construction, crews will update the lighting system inside the tunnel and add radar to detect speeders.

A warning system to alert drivers to traffic inside the tunnel, which aims to reduce crashes, will be the first in Los Angeles County. It will tell drivers to slow as they approach.

New signs in the area will also be installed and new pavement will be laid in the tunnel.
