I-10/Cypress Avenue Overcrossing Caltrans EA 46770

This project led by the City of Fontana constructed a new 4-lane overcrossing structure over Interstate 10 (I-10) on Cypress Avenue, between the Sierra Avenue and Citrus Avenue interchanges in the City of Fontana.  The $13 million project was designed to provide a means for north and southbound traffic in the City to cross over I-10 without having to travel through heavily congested interchanges.  This provided much needed relief for motorists traveling over I-10 as well as pedestrians and children going to and from a high school and a middle school located between Cypress and Citrus Avenues on the south side of I-10.

This project extended Cypress Avenue from Valley Boulevard southerly to Slover Avenue and over two transcontinental railroad tracks operated by Union Pacific Railroad (UPRR).  It also required relocation of a main sewer line under I-10, which passed immediately under the location of the bridge columns and abutments for the overcrossing.

Right of Way acquisition for this project was complicated due to the City performing the acquisition of all property rights and negotiations with UPRR to obtain an aerial easement over the tracks and execute a Construction and Maintenance agreement, which was the first the City had ever done.  Right of Way mapping also proved to be a challenge for the City, which they eventually overcame.   Titles are being transferred to the State where appropriate.

The project was funded using a combination of local and Federal funds to complete development and construction.  This project was completed approximately 3 months ahead of schedule.

The Southtstar project manager delivered the PA/ED, PS&E, Right of Way and Construction phases on-time and within the support budgets programmed for the project.   He worked closely with City staff to make sure all project design and right of way issues were understood and responded to in a timely and appropriate fashion.
