The project consists of applying asphalt in various locations from the Calistoga city limits to the Napa County line.
The road will be open to travel at all times during construction. However, there will be short periods of time where traffic is limited to one-way travel with a flag person at either end of the work area. The County acknowledges that construction may pose a minor inconvenience for a short period of time and appreciates the patience of the surrounding community. It is recommended that motorists seek out alternate routes during construction or simply allow for more travel time between destinations.
