Motorists can expect multiple lane closures along eastbound San Marcos Boulevard from Viewpoint Drive to Knights Realm and westbound  San Marcos Boulevard from Knights Realm to Rancho Santa Fe Avenue through Monday, Aug. 20. These closures will accommodate major roadway repair work resulting from a water main break that occurred on Tuesday, July 24.

As of Wednesday, Aug. 8, repair work is on schedule. Vallecitos Water District and the City are working together to complete repairs as quickly as possible. Extended construction hours have been approved and will be 5 am to 8 pm, Monday through Saturday in order to complete all repairs in advance of the fall school year.

Mapped traffic alert for San Marcos Boulevard on July 30Both turn lanes onto southbound Rancho Santa Fe Road from westbound San Marcos Boulevard will also be closed to traffic. To access southbound Rancho Santa Fe Road, detours will be in place directing traffic to make a U-turn at Viewpoint Drive and Acacia Drive.

Although through traffic will be maintained along San Marcos Boulevard, intermittent detours may be added throughout the construction period to help keep traffic moving. Closures will change frequently and the duration will vary due to the amount and complexity of the required roadway repairs.

Standard traffic control measures with advanced warning signs and pedestrian detours will be in place. Significant traffic delays are anticipated and motorists are strongly encouraged to use alternate routes whenever possible.

Motorists are urged to follow all traffic control measures, plan for extra time to arrive at destinations on time and drive with caution through the work area; delays in the schedule may occur.

According to Vallecitos Water District, the water main break was caused by a decades-old corroded pipe.
