While much of this work happens out of sight, local residents may notice construction zones, lane closures and maintenance vehicles throughout Jefferson County this year. By replacing and expanding these systems now, Jefferson County hopes to reduce future overflows and improve reliability for nearby neighborhoods. That’s why Jefferson County crews enlist the help of a tiny robotic camera! It’s one of the reasons you may occasionally see maintenance trucks parked over manholes or temporary lane closures around Jefferson County.
