An estimated $16.5 million will be spent on repairing a tunnel at the 2 and 5 freeways that was damaged last month from the intense heat generated by a gasoline tanker-truck that caught fire in the passageway.
The damage estimate for the Elysian Valley freeway tunnel was revealed by Carrie Bowen, acting director of Caltrans District 7, in a blog post on the highway agency’s website. The repairs are expected to begin in October and completed before Christmas, according to Bowen.
The damaged tunnel connects the northbound 2 freeway to the northbound 5 freeway. The Caltrans blog provided details of the repairs:
- Hydrodemolition will remove any degraded concrete from the surface of the structure.
- Shotcrete is a slurry of concrete 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.
- Repave the damaged roadway.
- Upgrade the connector’s lighting, metal beam guardrail, and add anti-graffiti coated paint.
Caltrans did not say whether the repairs would require any lane closures.
