Traffic Impacts Planned for Two Escondido Sites During Aqueduct Upgrades
Starting the second week of August, pedestrians and motorists in Escondido will notice traffic impacts due to construction work on Water Authority facilities as part of the Southern First Aqueduct Facilities Improvement project.
Beginning on August 11, work will take place on Bear Valley Parkway just north of San Pasqual Valley Road where a traffic lane and a bike lane on Bear Valley Parkway will be closed, Monday through Friday from 7 a.m. to 5 p.m.
At a second site on Harding Street, just north of the intersection with East Valley Parkway, traffic will be rerouted in the evenings starting on Aug. 18. The southbound traffic lane, left turn lane, and #1 northbound lane will be closed for nighttime construction from 5 pm to 7 am, Monday through Friday.
Signs and flag crews will help direct traffic around the work areas. Construction activities will include excavation, saw cutting, welding, concrete placement, backfill and paving. Work crews will be driving heavy construction equipment with required backup alarms

Work at each of these locations is estimated to last four weeks.
This is part of the Water Authority’s work to upgrade the historic First Aqueduct and ensure continued delivery of safe and reliable water supplies for the region.
The Southern First Aqueduct project stretches 21 miles starting north of Escondido and east of Interstate 15 and continuing south to Slaughterhouse Canyon on the west and ending at the San Vicente Reservoir in Lakeside. Along the way, the work crosses the communities of Escondido, Poway, Rancho Bernardo and parts of unincorporated San Diego County.
The First Aqueduct has been in service over 70 years and serves more than 2 million people countywide. Work around the region to improve the First Aqueduct is expected to continue through summer 2026 with upgrades to 99 structures connected to two massive water pipelines.
The Water Authority is coordinating closely with its member agencies to minimize impacts to residents and businesses and ensure there is no interruption to water delivery.
