Highway 99 Widening, Caltrans On-Call

NV5 and its team provide on-call construction engineering, inspection, and material testing services for Caltrans District 10 (Central Region), with up to 30 individuals assigned throughout the district at any given time.

For example, we are providing construction inspection, materials testing, and office engineering for the $152 million series of projects that will ultimately widen 11 miles of Highway 99 from four to six lanes and construct new interchanges at Lathrop Road and French Camp Road. The project runs from south of Highway 120 to north of Arch Road.
