Document Description
The County of Riverside Transportation Department proposes to
perform emergency repairs on Ramon Road Overhead Bridge, which is over railroad tracks. The
project area is near the City of Rancho Mirage, approximately 0.15 mile West of the I-10
freeway and 0.2 mile East of Bob Hope Drive, in the Community of Aqua Caliente/Thousand
Palms in the County of Riverside. Significant signs of erosion and cavities were observed at the
easterly Abutment 4 from the bridge approach deck. Further investigation revealed that these
cavities were caused by a failure in the abutment backwall drainage system. This failure allowed
rainwater runoff from the bridge deck to seep through the backwall drainage system and exit
through the abutment stem weep holes, resulting in the undermining of the abutment footings
and severe erosion along the slopes.
The County of Riverside Transportation Department proposes to perform emergency repairs to fix
the issues. The proposed emergency repairs include the following:
1. Stabilize the undermined foundations:
Stabilize the bridge foundations by placing slurry underneath the undermined footings and along
the eroded slopes. Placing the slurry will require temporary bulkheads to be installed to contain
the slurry along the slopes.
2. Reinstall the abutment backwall geo-composite drainage systems:
The abutments on both sides will be excavated to a depth and width sufficient to install the new
geo-composite drainage systems along the abutment backwalls. After the drainage system
installation, the excavated area will be backfilled with structural compacted soil backfill, and the
new road pavement surface will be placed.
