Lane shifts continue with storm drain construction along North Coast Highway 101 from Jupiter Street to La Costa Avenue
The City of Encinitas is continuing to construct drainage infrastructure to minimize flooding along the North Coast Highway 101 corridor. The City appreciates the City Council’s approval of additional funding to support this critical storm drain work. Construction of the Leucadia Streetscape 60-inch and 66-inch storm drain pipes is progressing northward along North Coast Highway 101, with work expected to continue through Summer 2025.
Once the large storm drain is installed between Jupiter Street and La Costa Avenue, work will begin on the collector drains, smaller storm drains and inlets, water line replacement, and new curbs, gutters, and sidewalks. This next phase is anticipated to start in Summer 2025 and be completed by Summer 2026, pending weather conditions.
PROJECT DETAILS
-
Current Work: Crews are continuing to excavate and install large storm drain pipes (60-inch and 66-inch) between Jupiter Street and La Costa Avenue. This work also includes cleanout boxes and pipe extensions. To minimize traffic disruptions, part of the installation will be done by tunneling under the La Costa Avenue intersection.
-
Traffic Adjustments: Northbound traffic at Jupiter Street will remain shifted to the west side of North Coast Highway 101, allowing two-way traffic to flow up to La Costa Avenue. Curbside parking on the west side will be temporarily restricted, and north bound traffic will return to the east side at La Costa Avenue.
-
Work Planned: Pipe installation and related work, such as storm drain inlets and connector pipes, will continue north of Moorgate Road through Summer 2025. Crews will be working at multiple locations between Jupiter Street and La Costa Avenue.
TRAFFIC CONTROL MEASURES
To ensure the safety of the community and construction crews, traffic control measures will be in place throughout construction, including:
- Cones, delineators, and signs
- Lane shifts and closures
- Flaggers directing traffic
- Concrete barriers
SAFETY REMINDER
During the construction period, please expect intermittent lane shifts and closures, large construction equipment in the work zone, and temporary noise. We urge all drivers, bicyclists, and pedestrians, to follow marked signage and proceed with extra caution to ensure the safety of everyone, including cyclists and pedestrians. For compliance with construction regulations and for safety reasons, only construction personnel are allowed within the construction zone along the east side of the roadway and within the median.
Thank you for your patience and cooperation as we work to improve our infrastructure.
