You may have seen the roadwork already. SDG&E is replacing a 2.5 mile segment of aging underground electric cable system installed 40 years ago. The cable system is one of the oldest in the city.
The project replaces the cable system from the substation near Eads Avenue and Pearl Street to an existing overhead transmission pole atop Mount Soledad (near the intersection of La Jolla Scenic Drive and Soledad Park Road.
The utility company estimates the project will cost $15 million to $18 million and estimates it will take four to eight months to complete.
Trenching work will occur during the day and cable work will be performed at night. No streets will be completely closed and access to business and homes will be maintained. Some streets will require traffic control flaggers to maintain a safe traffic flow.
No outages are anticipated and traffic lights are not anticipated to be impacted.
Crews will trench approximately 13,600 feet of city streets and install the new cable systems as well as nine underground vaults to facilitate future maintenance, an SDG&E spokesman said.
Construction passes both La Jolla High School and Muirlands Middle School. SDG&E said it arranged the construction schedule to avoid as much of the school year as possible.
Crews began trenching at the east end of Nautilus Street and work their way down the hill towards Eads Street. This part of the project is targeted for completed by the beginning of September. In September, crews will then trench from the east end of Nautilus up the hill along La Jolla Scenic Drive to Via Capri.
All trenching is anticipated to be completed by the end of October and all streets will be “restored to pre-construction conditions,” SDG&E reported.
