- (1) Permits are required for all vehicles or combinations of vehicles, including any load, which exceeds 14 feet in height. Unless specifically stated on the permit as authorized by ORS Chapter 818 or rule, over-height permits will not be valid for loads or items placed or stacked one on top of another or overlapping.
- (2) The height of a permitted load is measured from the ground to the highest point as it is ready for transport on the highway.
- (3) Vertical clearance through or under structures for over-height permitted loads is allowed to be up to, but within no more than four inches of the lowest determined physical clearance for each traffic lane of each structure. Over-height loads are routed under or around structures according to this maximum buffered vertical clearance.
- (4) The Chief Engineer or designee of the Department of Transportation Bridge Engineering Section is responsible for obtaining and maintaining accurate vertical clearance measurements under all Oregon highway structures.
- (5) The Chief Engineer authorizes the Administrator of CCD to approve a route and issue a permit resulting in maintaining less than a four inch buffer distance between the load and the structure on a case by case basis only after reviewing vertical clearance measurements and determining issuance of the permit is reasonable. Permits issued under this subsection will be valid only for the single specific movement requested and approved unless otherwise authorized by the Administrator. Permits issued under such conditions may require coordination and monitoring by Department of Transportation staff as designated.
