San Miguelito Road in Lompoc reopened after more than a year of closure.
Heavy rains during the January 9th storm in 2023 eroded the embankment and caused a culvert underneath to fail, according to a Santa Barbara County spokesperson.
The road is the only access to the Strauss Wind Farm Project outside Lompoc.
A mini steel bridge was initially built to help with the transportation of windmill blades to the wind farm.
County officials said crew members later installed a new steel pipe through the embankment to act as a new culvert and installed a new drainage system.
