In the case of a plan which requires access to a highway under
the jurisdiction of the Department of Transportation, the inclusion
of the following plan note:
"A highway occupancy permit is required pursuant to Section
420 of the Act of June 1, 1945 (P.L. 1242, No. 428), known as the 'State
Highway Law,' before access to a state highway is permitted. Access
to the state highway shall be as authorized by a highway occupancy
permit, and the Supervisors' approval of this plan in no way
implies that such a permit can be acquired."
