Chapter 734

Rule Caption: Maximum allowed tow length for mobile homes traveling on U.S. Route 95.

Adm. Order No.: HWD 6-2011

Filed with Sec. of State: 6-21-2011

Certified to be Effective: 6-21-11

Notice Publication Date: 5-1-2011

Rules Amended: 734-075-0010

Subject: A petition for rulemaking was received from the Oregon Manufactured Housing Association, requesting a revision to 734-075-0010 to make permanent allowance of mobile homes up to 80 feet in length when traveling between Idaho and Nevada on US Route 95. The rule previously limited mobile home length to 75 feet. During a temporary allowance, towed 80-foot long mobile homes traveling on U.S. Route 95 were observed in order to evaluate safety issues and road damage. There were no safety problems reported and the highway was not adversely affected by the movement of the 80-foot long mobile homes. OMHA stated that the ability to use US Route 95 to travel between Idaho and Nevada saved the carrier approximately 200 miles of out-of-route travel per trip, along with fuel and other associated cost savings.

(c) The mobile home may be up to 80 feet in length, including the tongue, when the unit will be transported through Oregon on US-95.

(3) The maximum widths are as follows:

(a) Units must not exceed 14 feet overall width, unless a single trip permit or a limited duration permit is issued;

(e) A unit that exceeds 16 feet wide at the base may be allowed if the Administrator of MCTD determines that the public interest requires the impending movement, and the movement can be performed safely.

(4) Except as provided in subsection (5), the maximum height for the combination, while in transit, must not exceed 14 feet unless proper route clearance has been obtained and is so indicated on the single trip permit.

Rule Caption: Modular building unit trailer lengths.

Adm. Order No.: HWD 7-2011

Filed with Sec. of State: 6-21-2011

Certified to be Effective: 6-21-11

Notice Publication Date: 5-1-2011

Rules Amended: 734-075-0025

Subject: This amendment provides an exception to allow an over-dimensional permit to authorize modular building trailers in lengths up to 75 feet that are fixed in length to be used for unladen (empty) return trips. The industry has modified trailers that are fixed in length to transport modular buildings units. The rule change is necessary to accommodate modified trailers needed to transport increasingly larger modular buildings.

Hauling Vehicles for Modular Building Units

The following requirements apply to vehicles hauling modular building units:

(1) Modular Building Units must be hauled with a truck-tractor and semitrailer or trailer combination.

(2) Equipment weights of the combination and the sizes and ratings of all its components must be comparable to those commonly used by the motor carrier industry in general over-the-road trucking operations.

(3) When operating unladen, the overall length of the combination must not exceed the length authorized by statute or rule, except as authorized in the permit.

(4) Modifications are permitted to the conventional equipment necessary for hauling modular building units. This may include “stretch-trailer” features, adjustable trailer heights from inflatable air bags, steering capabilities for the semitrailer axles or other modifications. These features must be stipulated in the permit.

(5) Requests for moves using trailers more than 53 feet in length will be on an individual basis, and permits will be issued for a single trip only. The authorized trailer length must be stipulated in the permit and must not exceed 75 feet in length, except when using a stretch trailer. When not operating under the terms of a permit issued under this rule a stretch trailer must be reduced to dimensions authorized by statute or rule.

(6) The modular building unit must be securely fastened to the semitrailer or trailer. It may be secured by steel cables and winch tighteners, steel cables or chains and chain binders, or by adequate bolting directly to the semitrailer or trailer frame. Alternate securing methods approved by the United States Department of Transportation regulations may be used.

Rule Caption: Permits for vehicles that exceed the legal vehicle height.

Notice Publication Date: 5-1-2011

Rules Amended: 734-082-0025

Subject: The amended rule specifies the Department of Transportation Bridge Section as the responsible group for providing accurate vertical clearance measurements under all structures. Department policy for vertical clearance is to provide a 4-inch buffer zone between the structure and the load for cautionary purposes. In addition, the amendment allows the Chief Engineer to authorize the Administrator of the Motor Carrier Transportation Division to approve routes and issue permits for loads that encroach on the prescribed 4-inch buffer on a case by case exception basis taking into account the measurements provided by the Bridge Section. The amended rule assigns responsibility to the MCTD Administrator to research and approve over-height permits for the rare cases where the load will encroach on the 4-inch buffer and an alternative route is either not desirable or readily available.

Height

(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 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 the Motor Carrier Transportation Division 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.
