Design

The Engineering Design Section develops roadway designs using local and state guidelines required for traffic volume, terrain, design speed, safety features, storm water runoff, and environmental concerns. Design production may be handled in-house or by contractors. Designs for new bridges are contracted to a structural engineer.

Once the designs are complete, staff members help prepare contract specifications for open and competitive bidding by road and bridge construction companies. Inspection of contractors' construction operation are also handled by the staff from the Design, Construction, and Survey Sections.
