Project Description

The U.S. Highway 50 Multimodal Corridor Enhancement and Rehabilitation Project was a comprehensive infrastructure initiative undertaken by the California Department of Transportation (Caltrans) to improve mobility, safety, and sustainability along a critical stretch of U.S. Highway 50 in Sacramento. This project focused on a segment extending from the Interstate 5 Interchange to the Watt Avenue Interchange, covering approximately 7 miles of urban freeway.

Knight CM Group personnel provided comprehensive construction management services for the project, ensuring that all aspects of construction adhered to strict safety, quality, and regulatory standards. Our team oversaw the coordination of multiple contractors, managed scheduling and cost controls, and ensured seamless execution of the project’s various phases.

Key components of the project included the addition of High-Occupancy Vehicle (HOV) lanes in both directions to promote carpooling and reduce congestion during peak travel times. The project also rehabilitated 54 lane miles of pavement, replacing aging concrete with continuously reinforced concrete pavement to enhance durability and provide a smoother driving experience.

To accommodate modern transportation needs, the project involved the widening of 12 bridges and the construction of three miles of retaining walls to improve structural integrity and support the expanded roadway. The project also improved freight movement efficiency by increasing vertical clearance at seven overcrossings, facilitating the passage of larger vehicles and enhancing the movement of goods through the corridor.

Environmental considerations were a key aspect of the project, with efforts made to reduce greenhouse gas emissions and promote multimodal transportation options. The inclusion of sound walls along residential areas, particularly between Stockton Boulevard and 65th Street, helped mitigate noise pollution and improve the quality of life for neighboring communities.

Additional improvements included enhancements to connector ramps, ramp widening at three locations, and the rehabilitation of three pumping plants to manage groundwater effectively. Upgrades to signage, lighting, and intelligent transportation systems improved safety and traffic management throughout the corridor.

With the successful completion of the U.S. Highway 50 Multimodal Corridor Enhancement and Rehabilitation Project, traffic flow was significantly improved, congestion was reduced, and travel became safer and more efficient for both commuters and freight transportation. Knight CM Group personnel ensured the project was delivered on time and within budget, representing a substantial investment in the region’s transportation infrastructure and demonstrating a commitment to sustainable development and enhanced mobility for all users.
