Work to extend a retaining wall on a steep section next to Jimmy Durante Boulevard is running behind schedule, with delays attributed to unforeseen utility coordination issues and challenging environmental factors. The project requires weekday lane closures on the northbound side of the road, anticipated to continue through September.
The delayed construction affects the stretch between Luzon Avenue and David Way, where intermittent road closures will occur Monday through Friday from early morning until late afternoon. City officials emphasized efforts to avoid disruptions during the busy San Diego County Fair period, suspending closures from June 10 to July 5.
The retaining wall extension follows a damaging bluff failure that occurred on Easter Sunday in 2019, which led to an emergency installation of the original steel beam and timber lagging wall. Recent geotechnical evaluations have called for a 45-foot extension of the wall to improve slope stability and prevent future collapses.
In addition to reinforcing the bluff, the project encompasses drainage upgrades and landscaping improvements designed to enhance long-term durability and visual appeal. Traffic detours reroute northbound vehicles from Jimmy Durante Boulevard onto Camino del Mar and Via de la Valle. Drivers are reminded to comply with posted signs and detour routes to ensure safety and smooth traffic flow.
Residents and commuters seeking updates or assistance can contact Del Mar Public Works directly via phone or email for further information regarding the retaining wall project timetable and impacts.
