Clay Street is a four-lane Major Highway located in the City of Jurupa Valley that connects Limonite Avenue to the north and Van Buren Boulevard to the south.  A Union Pacific Railroad (UPRR) at grade crossing currently exists on Clay Street just east of Van Buren Boulevard.  The Riverside County Transportation Department in conjunction with the City of Jurupa Valley propose to grade separate the current at-grade crossing  by lowering the roadway under the railroad tracks.  Although currently in the City of Jurupa Valley, the project was initiated by the County prior to incorporation of the City and the City and County have arranged for the County to continue as lead agency through the completion of this project.

The project includes reconstruction of Clay Street to pass under the existing UPRR railway, construction of a railroad bridge (60’ wide, 104’-7 5/8” long,  two span) for the existing UPRR railway, and lowering of grade elevation at General Drive and at Linares Avenue that will tie into the new lower Clay Street grade. The UPRR bridge will be approximately 105 feet long and 60 feet wide.  A new traffic signal will be constructed at Linares Avenue and a separate project will construct a new signal at General Drive.  Construction will also require a temporary shoo-fly track adjacent to and north of the existing UPRR mainline. A shoo-fly is a temporary by-pass necessary to maintain rail circulation through the project area during construction of the new structure.  Upon completion of the structure, the shoo-fly will be removed.

Purpose & Need

Clay Street carries over 17,000 vehicles per day.  30 freight and 12 passenger trains also pass through the Clay Street grade crossing on a daily basis, which is projected to increase to 45 freight and 28 passenger trains by 2030. The increase in number of trains will cause frequent interruptions in the normal flow of highway traffic. Traffic congestion in the area may increase potential train/vehicle accidents.

This grade separation project will improve vehicular traffic circulation and safety and will provide uninterrupted and efficient access for motorists, residents, businesses, pedestrians and emergency vehicles in the area.   Additionally, the project will also enhance the operational characteristics (i.e. speed, efficiency, and reliability) of freight and passenger trains through Riverside County by eliminating conflicts between railroad operations and vehicular traffic.
