Fresno Bridge Job

In Northern California in 2021, Stronghold replaced a bridge that supports the UPRR tracks over Laguna Creek in Elk Grove, California. Working just 15 minutes south of the State Capitol in Sacramento, the team built a trestle in order to maneuver a crawler crane fitted with a soundproofed diesel pile hammer to ensure that the local community wasn’t disturbed.

Using the crawler crane, the team drove approximately 33 hollow section, 24″ steel tube piles into the ground for support while the current bridge is in operation until the change out and replacement of the bridge deck.

At Stronghold, we’re proud of our team members and grateful to every one of them for helping us achieve new heights this past year. With their help, hard work and support, Stronghold is looking forward to another banner year in 2022.
