Scope Of Work

Washington Boulevard is a major east-west corridor that serves as one of the significant connectors between the I-710 and I-5 Freeways carrying approximately 35,000 vehicles per day, 25% of which is truck traffic.

This segment of roadway is the key link in the regional movement of goods from the ports of Los Angeles and Long Beach to the terminals of the Union Pacific Railroad and Burlington Northern Santa Fe Railways. The job was a reconstruction and widening project covering a 2.7-mile segment of Washington Boulevard between Indiana Street to the Santa Ana (I-5) Freeway. The project was to improve truck circulation and current level of service operations by reducing delays and traffic while improving the overall air quality. It would widen the mentioned segment from two lanes to three lanes in each direction, which would allow for an increase in the turning radius and larger medians for better traffic flow.

Geo-Advantec was selected as the Caltrans certified laboratory and provided field inspection/testing and laboratory testing in compliance with Caltrans Local Assistance Manual. Our team performed testing and inspection on flexible and rigid pavements per the project/Caltrans requirements. We also measured the compressive and flexural strengths of different types of concrete pavement components. The project duration was about 24 months and the construction cost was approximately $30M.
