Section A. Section 304.180, RSMo, is repealed and one new section enacted in lieu thereof, to be known as section 304.180, to read as follows:
304.180. 1. No vehicle or combination of vehicles shall be moved or operated on any highway in this state having a greater weight than twenty thousand pounds on one axle, no combination of vehicles operated by transporters of general freight over regular routes as defined in section 390.020, RSMo, shall be moved or operated on any highway of this state having a greater weight than the vehicle manufacturer's rating on a steering axle with the maximum weight not to exceed twelve thousand pounds on a steering axle, and no vehicle shall be moved or operated on any state highway of this state having a greater weight than thirty-four thousand pounds on any tandem axle; the term "tandem axle" shall mean a group of two or more axles, arranged one behind another, the distance between the extremes of which is more than forty inches and not more than ninety-six inches apart.
2. An "axle load" is defined as the total load transmitted to the road by all wheels whose centers are included between two parallel transverse vertical planes forty inches apart, extending across the full width of the vehicle.
3. Subject to the limit upon the weight imposed upon a highway of this state through any one axle or on any tandem axle, the total gross weight with load imposed by any group of two or more consecutive axles of any vehicle or combination of vehicles shall not exceed the maximum load in pounds as set forth in the following table:

Notwithstanding the above table, two consecutive sets of tandem axles may carry a gross load of thirty-four thousand pounds each if the overall distance between the first and last axles of such consecutive sets of tandem axles is thirty-six feet or more.
4. Whenever the state highways and transportation commission finds that any state highway bridge in the state is in such a condition that use of such bridge by vehicles of the weights specified in subsection 3 of this section will endanger the bridge, or the users of the bridge, the commission may establish maximum weight limits and speed limits for vehicles using such bridge. The governing body of any city or county may grant authority by act or ordinance to the state highways and transportation commission to enact the limitations established in this section on those roadways within the purview of such city or county. Notice of the weight limits and speed limits established by the commission shall be given by posting signs at a conspicuous place at each end of any such bridge.
5. Nothing in this section shall be construed as permitting lawful axle loads, tandem axle loads or gross loads in excess of those permitted under the provisions of Section 127 of Title 23 of the United States Code.
6. Notwithstanding the weight limitations contained in this section, any vehicle or combination of vehicles operating on highways other than the interstate highway system may exceed single axle, tandem axle and gross weight limitations in an amount not to exceed two thousand pounds. However, total gross weight shall not exceed [eighty thousand] eighty-five thousand five hundred pounds.
7. Notwithstanding any provision of this section to the contrary, the department of transportation shall issue a single-use special permit, or upon request of the owner of the truck or equipment, shall issue an annual permit, for the transporting of any concrete pump truck or well-drillers' equipment. The department of transportation shall set fees for the issuance of permits pursuant to this subsection. Notwithstanding the provisions of section 301.133, RSMo, concrete pump trucks or well-drillers' equipment may be operated on state-maintained roads and highways at any time on any day.
