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.
