On Sunday, two large boulders slid down the hillside and landed on Southbound Highway 17 near the Redwood Estates area.
The boulders were over 800 pounds, and a Toyota Prius crashed into one of them.
The driver was not injured, however traffic was at a standstill as crews worked to clear the debris.
Delays as a result of this incident were well over an hour as traffic backed up as far as Campbell.
