AMENDATORY SECTION(Amending Order 183, filed 10/13/98, effective 11/13/98)
Maximums for special permits -- ((
(1) Overwidth: 14 feet on any two-lane highway; 20 feet on any multiple-lane highway where a physical barrier serving as a median divider separates the oncoming and opposing traffic lanes; 32 feet on any multiple-lane undivided highway.
The regulations on movement of buildings are in WAC 468-38-360.
(2) Overheight: A load over 14 feet high must be moved by permit, but the permittee is to be governed by the clearance of overhead obstructions such as bridges, underpasses, wires, overhead signs and other objects. The issuance of a permit does not insure the route to be free of low overhead structures. It is the responsibility of the permittee to check the proposed route and detour when necessary. County or city road detours for this purpose require authorization from respective jurisdictions.
(3) Overlength: The permit will allow movement on routes on which the permittee can negotiate curves, interchanges, entrance and exit roadways and other obstacles. In all instances the general safety of the public is considered paramount.
Overweight: 22,000 pounds on a single axle; 43,000
pounds on tandem axles. (RCW 46.44.091))) Loading restrictions:
The load must be reduced to a practicable minimum, even if
additional vehicles are required to transport the divided item.
Loads created by welding, bolting or tying will be construed as
divisible, unless proven with good cause not to be divisible.
(5) Overweight loads: Restricted to the limits established in RCW 46.44.091 Special permits -- Gross weight limit. In addition, tire loadings are limited to a maximum of six hundred pounds per inch width of tire.
(6) Allowable vehicle configurations:
(a) Tractor (or unladen truck) and semi-trailer or full trailer. Jeeps and/or boosters may be added to the trailer as necessary. Trailers in excess of the legal width of eight feet six inches, or legal length of fifty-three feet, or the permitted length of fifty-six feet, shall not exceed the length or width of the load, unless, the added dimension is necessary to spread the weight of load to comply with requirements established by the department to protect the infrastructure. A "pusher" power unit may be added to the configuration upon approval.
(b) Tractor with semi-trailer and full trailer. Combined trailer length, including space between trailers, may not exceed sixty-one feet. This combination is limited to nondivisible loads not to exceed ten feet wide. Both trailers may carry nondivisible loads with the widest load contained on the first trailer. This configuration may not carry over-height, over-length or over-weight loads.
(c) Truck and trailer. Combined overall length when carrying an over-length load may not exceed eighty-five feet, with the nondivisible over-length load restricted to the trailing unit, overhang loaded entirely to the rear of the trailer. An over-width or over-height nondivisible load may be carried on the truck and/or trailing unit. This configuration may not carry overweight loads.
(7) Loads with multiple pieces: An over-dimensional load may include multiple pieces, provided:
(a) The vehicle(s) and load are transported at legal weights.
(b) The largest nondivisible piece(s) must be loaded to its practicable minimum. No single piece may create a dimension greater than the dimension it would create if carried by itself.
(c) Additional pieces may not exceed the outside envelope (rectangular) dimension created by the largest piece(s) loaded in its smallest configuration. No piece shall be added to a load for the sole purpose of creating a larger envelope. It shall be the responsibility of the carrier to provide proof that all pieces are necessary to the move.
