Road Conditions and Closures

Nevada County Public Works strives to post road conditions and closures for significant traffic control situations and/or closures related to construction, severe weather-related events, and/or emergencies on county-maintained roads only during office hours. While we attempt to provide as much information as possible, Nevada County does not guarantee that the information provided is accurate or complete. Access to this data is at the user's risk.

For continuous travel in construction zones, please observe all traffic control signs and the instructions of onsite personnel. We apologize for any inconvenience this may cause and appreciate your patience.
