Routine Maintenance
Our maintenance team provides a variety of services year-round to keep our 1,400 miles of county roads safe, reliable and easy to navigate.
Bridge Maintenance
Our 186 bridges are inspected every 2 years and through those inspections we sometimes find repair and maintenance work that needs to be done to preserve the bridge structure and keep it safe for travelers. That work often includes bridge scour projects, either removing excess soil from stream channels or replacing soil around foundations that has been washed away during high water events.
Pavement Rehabilitation
Pavement rehabilitation includes treatments that extend the life of an existing road surface such as surface sealants, patching short spans of roadway and asphalt paving. These proactive measures add structure to the road, remedy pavement distresses, and maintain a road's condition to defer full reconstruction further in the future. See schedule for next five years.
