Department of Transportation

The Department of Transportation is responsible for the funding, planning, designing, building, operating and maintaining the County Road System (CRS).  The County Road System currently consists of approximately 1083 centerline miles of paved roadway, 76 bridges, a ​multitude of storm drainage systems and related transportation facilities.

The ​two primary priorities of the Department of Transportation are:

  1. Public safety - ensuring that our roads are safe for public use with due care in a manner in which it is reasonably foreseeable that they will be used.

  2. Preservation of infrastructure - preserving and maintaining the public's multi-billion dollar investment in our roads, bridges and other facilities associated with the CRS.
