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.

This rule establishes the maximum number of vehicles in
combination and size of vehicles allowed when moving an over-dimensional unit:
(1) The combination must not exceed two vehicles, the
towing vehicle and the unit being transported.
(2) The maximum lengths are as follows:
(a) The maximum overall length of the combination must:
(A) Not exceed 85 feet on State highways;
(B) Not exceed 95 feet on Group 1 highways; and

multilane highways or highways approved for the longer length as authorized by
a single trip permit or as authorized by written order of the Chief Engineer.

feet, including the tongue, except as provided in subsection (c) or OAR
734-075-0011.
(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;
(b) Units transported under a single trip permit or
limited duration permit are subject to the following:

(A) More than 30 inches for units with a base width of
less than 16 feet; or
(B) More than 16 inches for units with a base width of
16 feet or more.
(d) External appurtenances such as doorknobs, window
fasteners, eave cap, clearance lights and load securement devices may exceed
the width of the unit by a distance not greater than two inches on each side;
(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.

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.

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.
