Document Description
On Interstate 8 (I-8) in the unincorporated community of Flynn Springs, County of San Diego, this Director’s Order Emergency Project proposes to repair roadway settlement and a sinkhole. The 12.5-foot diameter corrugated like steel pipe culvert conveys waters from Los Coaches Creek has failed and caused a sinkhole in the median and settlement between the No. 1 and No.2 lanes of westbound I-8. The sinkhole will be excavated to a depth of 15-feet and will be backfilled with slurry. The invert of the culvert will be paved with concrete and voids under the pipe will be filled in at the same time. Grouting will take place inside the pipe to fill voids up to the springline. Compaction grouting will be done from mainline to fill any remaining voids outside of pipe.
