2/5 Connector Repair Project Begins

Caltrans has awarded C.A. Rasmussen Inc. of Valencia, California, the construction contract to begin repair work on the tanker fire damaged northbound SR-2 to northbound I-5 connector.  The contractor is expected to begin working on Tuesday, November 5.  The overall cost of repairs, which includes the initial emergency response, is currently estimated at $16.5 million. 

“We understand that the closure of any part of the freeway system can inconvenience motorists,” said Acting District 7 Director Carrie Bowen.  “We have an ambitious and aggressive construction schedule in place to safely open this connector before Christmas.”

The following solutions will be used to repair the connector:

Caltrans engineers meeting with the contractor during a pre-job meeting.
  • Hydrodemolition will remove any degraded concrete from the surface of the structure.
  • Shotcrete is a concrete slurry that is sprayed at a high velocity to fill damaged voids.
  • Epoxy injections will help seal cracks in the concrete and provide additional strength to the structure.
  • Carbon fiber wrapping will help add strength to the outrigger beams on the north side of the connector.
  • Repave the damaged roadway. 
  • Upgrade the connector’s lighting, metal beam guardrail, and add anti-graffiti coated paint.
The intense heat from the tanker fire on July 13 caused extensive damage to the pavement, walls, support structures, drainage, and lighting within the northbound SR-2/northbound I-5 connector tunnel, requiring it to be closed.
