I-10/Citrus Avenue Interchange Caltrans EA 46810

This project proposes to widen the Citrus Avenue Overcrossing from 5 to 8 lanes over Interstate 10 (I-10) and reconfigure the I-10/Citrus Avenue interchange in the City of Fontana.  This $47 million project will provide additional lanes on Citrus 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 Citrus 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 a large Ford automobile dealership 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.

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 Citrus Avenue and the ramps, as well as drainage, electrical and traffic facilities.  This is a gateway corridor in the City of Fontana, so special aesthetics were incorporated into the bridge rails and in the landscaping the areas between the ramps and the mainline.

Federal, State and Local funding sources were utilized to complete development and construction of this important interchange project.  Multiple Federal sources, including Local Surface Transportation Program and Congestion Management/Air Quality funds, State STIP and Transportation Corridor Improvement Funds, local Measure I and City and County funds have been used throughout all phases of this project.  Because of funding changes, several cooperative agreements and amendments were required to make sure adequate funding was provided for this project.

The Southtstar project manager delivered the PA/ED, PS&E, and Right of Way phases on-time and within the support budgets programmed for the project.   He worked closely with SANBAG, County of San Bernardino and City of Fontana staff to make sure all project design and right of way issues were understood and responded to in a timely and appropriate fashion.  This project is scheduled to begin construction in April 2012.
