San Dieguito Drive reopens after repairs

slope repairs on San Dieguito Drive

San Dieguito Drive fully reopened March 17, two days after a partial road failure left a guardrail hanging, exposed a sewer line and reduced the narrow road to one lane of travel.

Within hours on March 15, crews placed riprap and crushed rock on the washout to stabilize the slope and secure the sewer line.

On March 16, engineers and a geologist developed a plan to rebuild the roadway. Construction began almost immediately.

The failure coincided with heavy rains, but its cause remains undetermined and is unrelated to other SDG&E and City work on San Dieguito Drive.
