Tanker Fire Damaged Tunnel Tested

A team of Caltrans materials engineers.
Today, materials engineers from the Caltrans’ Materials Engineering and Testing Services began additional testing of the concrete of the northbound Glendale Freeway (SR-2) to northbound Golden State Freeway (I-5) connector.

This testing will help determine what solutions Caltrans will deploy to repair the SR-2/I-5 connector that was severely damaged during a gasoline tanker fire inside of the connector on Saturday, July 13.

Holes were drilled so that engineers could place a camera inside of the structure to determine the extent of damage.

Caltrans engineers place a ferroscanner onto a concrete outrigger beam on the north side of the connector.

Ferroscanners are used to find the location of rebar inside concrete.  It's similar to a stud finder.
