The Office of the Ocean County Engineer is responsible for 621 miles of County roads and 225 bridges and culverts spread throughout 33 municipalities.

The Department, which is a function of the Ocean County Board of Commissioners, is led by Ocean County Engineer Mark F. Jehnke. The Engineering Department works closely with the Ocean County Road Department and various private contractors to upgrade and modernize the County road network. Engineering projects are developed with an emphasis on safety for pedestrians and motorists. Ocean County has also partnered with the New Jersey Turnpike Authority to build new and expanded Garden State Parkway interchanges.

The Engineering Department staff also installs and maintains over 35,000 traffic signs and 400 traffic lights throughout the County. A new computerized effort will allow engineers to quickly identify and replace any worn or aging traffic signs.
