SANTA BARBARA COUNTY, Calif. - Drivers may run into some delays on a stretch of Highway 1 near Lompoc Wednesday.
Caltrans is replacing the Salsipuedes Creek Bridge and building a retaining wall and fish passage.
The project started almost a year ago and will continue this week with a traffic switch onto the new southbound bridge Wednesday.
Caltrans says the traffic signal in the area will be turned off temporarily.
A pilot car and flaggers will do traffic control from 9 a.m. to 3 p.m.
Once the traffic switch is done, the traffic signal will turn on again and allow for two-way traffic on the southbound bridge. Construction will begin later on the northbound bridge.
Oversized vehicles will need to take a different route during the project because the lanes were reduced to 11.5 feet in width, and there are no shoulders.
The full project is expected to be finished by the end of the year.
