The authority given by private act to highway commissions must be consulted along with the CUHL to determine what powers such highway commissions may exercise.  The private acts are effective with regard to the county highway commission and county highway department except where they conflict with the general law (particularly the CUHL).  County highway officials in doubt as to the officer or commission with authority over a particular issue should consult with their own attorney, the county attorney, or the legal staff of The University of Tennessee’s County Technical Assistance Service (CTAS).
