OCEANSIDE — State transportation workers shut down one side of state Route 78 near MiraCosta College today for emergency repairs.
The roughly two-mile eastbound section of the freeway between College Boulevard and El Camino Real in Oceanside is expected to be closed for at least three weeks as crews finish fixing nine storm-damaged culverts, according to Caltrans.
A sinkhole that formed under the westbound lanes following heavy showers prompted the closure of that side of the route in the area on March 15. Those lanes reopened this week.
“Crews have been working 24-seven and faced four days of delays when more rains fell in the region since the repairs began,” Caltrans spokesman Hayden Manning said. “Corrugated-steel pipes are being replaced with high-density plastic and concrete pipes.”
As repair personnel finishes the job, eastbound motorists will be detoured around the work site via El Camino Real, Vista Way, College Boulevard and Plaza Drive.
The total cost of the project is estimated to be $20 million, with the funds coming from the California Highway Operation and Protection Program. Culverts are regularly inspected and assessed as part of the state Highway Asset Management Plan, Manning noted.
