The Challenge
Expanding Critical Transportation Capacity on Southern California's Growing Freeway Network
The SR-210 corridor serves as a vital transportation artery connecting communities across San Bernardino County. With increasing traffic volumes and regional growth, the existing infrastructure required significant expansion to meet current and future demands.
Construction activities were performed across more than 8.2 miles of freeway and included:
- Widening of State Route 210 (addition of one mixed-flow lane in each direction)
- Widening of 18 existing bridges
- Interchange upgrades
- New sound walls
- Construction of new auxiliary, acceleration and deceleration lanes
To minimize disruption to the traveling public, much of the work had to be completed during weekends and nighttime hours.
In addition, all testing activities needed to comply with strict California Department of Transportation (Caltrans) standard.
The Solution
Comprehensive Construction Materials Testing Services
Ninyo & Moore, a SOCOTEC Company, delivered construction materials testing and special inspection services to support safe and compliant execution of the SR-210 Lane Addition Project.
Our team verified the quality and performance of materials throughout the scope of work, including pavement systems, structural components, and bridge infrastructure. All testing was performed in accordance with Caltrans test methods and frequency requirements, including the Caltrans Construction Manual, Standard Specifications, Special Provisions, and approved testing frequencies and methodologies. This helped ensure compliance with state regulations and project engineering standards.
