Carlsbad extends rock barrier to protect coastal road
Crews are placing multi-ton boulders below an eroding bluff beside southbound Carlsbad Boulevard, north of Encinas Creek Bridge.
The City of Carlsbad says construction is underway to extend an existing rock revetment about 192 feet along the west side of the road. The barrier is intended to slow erosion, stabilize the bluff and protect coastal access and the continued operation of southbound Carlsbad Boulevard.
Location: North of Encinas Creek Bridge, south of Solamar Drive
Work: Approximately 192-foot rock-barrier extension
Rock size: About 4 to 8 tons each
Schedule: Construction expected to continue through late 2026
Active erosion put the roadway at risk
A September geotechnical review found active bluff retreat and warned that additional instability could occur with little or no notice. Carlsbad declared a local emergency September 9 to expedite the limited stabilization work. A state environmental notice says crews may extend the project another 65 feet if field conditions require it.
The city’s October progress update says boulder deliveries will continue for several weeks. Separately, Carlsbad is studying longer-term options for a broader section of the coastal road, including alternatives to a previously estimated $280 million realignment concept. That analysis is expected in late 2027.
