PROJECT DESCRIPTION

S2 Engineering provided CM services on the Cherry Avenue Interchange Project in the Inland Empire. The $76 million project includes replacing the existing five-lane Cherry Avenue bridge over I-10 with an eight-lane bridge, from Slover Avenue to Valley Boulevard. The project has widened the bridge over the railroad tracks from four lanes to eight lanes and make improvements to on-and-off ramps. It has loop ramps added as auxiliary on ramps; utilities crossing through the bridges; ramps realigned in the first stage; access to businesses maintained at all times; well-coordinated lane closures of city streets and ramps, and the use of rapid strength concrete minimized with additional JCPC for stage construction. Intersection improvements made at the Cherry and Slover intersection and Cherry and Valley intersection, and other local street improvements.

The purpose of the project is to improve safety and operational efficiency of the I-10/Cherry Avenue interchange. This interchange is a modified diamond geometric layout with loop on-ramp and the ramps are controlled by traffic signals. High volumes of traffic including heavy trucks traveling on I-10, Cherry Avenue and local region and obsolete roadway and bridge features warrant total reconstruction of the interchange.

The S2 staff is directly involved in reviewing field documents, schedule review & analysis, preparing & negotiating CCOs, and coordination with the City of Fontana, CHP, UPRR, Caltrans Oversight Engineers, CT Traffic Operations, CT Safety Committee, utility companies, residents & businesses, among others on an ongoing and proactive basis. The project completed ahead of schedule in June 2014.
