I-10/Cherry Avenue Interchange, Caltrans EA 46800

This project proposes to widen the Cherry Avenue Overcrossing from 5 to 9 lanes over Interstate 10 (I-10) and reconfigure the I-10/Cherry Avenue interchange in the City of Fontana.  This $47 million project will provide additional lanes on Cherry Avenue between Valley Boulevard and Slover Avenue and reconfigure the westbound ramps to provide right turn access onto I-10 for both north and southbound traffic on Cherry Avenue as well as widen the ramps from two to three lanes to provide more capacity for turning movements.  This project also incorporates ramp metering for the entrance ramps and auxiliary lanes to compliment Caltrans’ I-10 Auxiliary Lane addition project (EA 49750).  Widening of the overhead structure over two transcontinental tracks owned by Union Pacific Railroad (UPRR) is also necessary to provide operational improvements and congestion relief.

Right of Way acquisition was complicated by the attempt to minimize impacts to local businesses adjacent to the interchange, including several trucking sales dealerships, a truck stop and repair facilities and a gas station, as well as the need for a new Construction and Maintenance agreement with UPRR and relocation of several above ground and underground utility facilities.  Southern California Edison had transmission, distribution and telecommunication lines to move, which complicated utility relocations and there was a major fiber optic communication line within the UPRR right of way that had to be moved to avoid the bridge abutment for widening of the overhead structure.

Design of this project was also complicated by the need to redesign the overcrossing structure midway through the project to clear the potential of 2 additional High Occupancy Toll lanes on mainline I-10. This caused redesigning the profile of Cherry Avenue and the ramps, as well as drainage, electrical and traffic facilities.  This is a gateway corridor in the City of Fontana and the main access corridor to the California Speedway racetrack, so special aesthetics were incorporated into the bridge rails the areas between the ramps and the mainline was landscaped.

Federal, State and Local funding sources were utilized to complete development and construction of this important interchange project.  Federal Interstate Maintenance Discretionary funds, State STIP and Transportation Corridor Improvement Funds (TCIF), local Measure I and City and County funds have been used throughout all phases of this project.  Due to the uncertainty of State TCIF being available for construction, SANBAG proposed to substitute other funds to make sure the project was fully funded.  This required several cooperative agreements and amendments to make sure adequate funding was provided.  Construction on this project began in November 2012.
