This road runs south from County Road 29 towards north Davis. As it enters the Davis city limits, crossing the Covell Drainage Channel, its name changes to F Street. For the entire distance, it parallels the train tracks.

County Road 101a is a part of the Yolo County Roads system and is a great way to see some of the town outskirts.

We Davisites call this the "F Street Extension", the city made it a nice ride in the early 90's. —StevenDaubert
