Field-proven experience.

The Lake Isabella Dam Safety Modification Project raised and strengthened the existing dam to address seismic stability and seepage concerns. Work spanned large-scale excavation, emergency spillway construction, labyrinth weir installation, embankment placement, and modifications to State Route 155.

The California High-Speed Rail CP-1 project constructed 32 miles of high-speed rail guideway from Madera County to south Fresno, the longest and most complex segment of the Central Valley program. Work included 33 structures, three major viaducts, grade separations, below-grade trenches, a highway realignment, and extensive utility and railroad relocations.

The California High-Speed Rail CP-4 project constructed 22 miles of high-speed rail guideway through the southern Central Valley, from the Tulare-Kern County line to north of the City of Shafter. Work included 11 grade separations and viaducts, 4 miles of BNSF railroad track relocation, 143 utility relocations, and at-grade guideway embankments designed for speeds of 220 mph.

The Laurel Street Overcrossing Replacement in Vallejo was Caltrans' first multi-span Accelerated Bridge Construction pilot and the first use of UHPC connections between precast elements in California.

The Famoso Bridge Replacement Project demolished and replaced the aging SR 46/99 separation bridge in Kern County, bringing the interchange to current Caltrans seismic and geometric standards.

The SR-91 Main Street Gore Area Regrade improved highway safety at the State Route 91 / Main Street interchange in Los Angeles County by regrading the gore areas at the eastbound on-ramp and off-ramp.
