How tall is your RV? Are you including the AC unit on the top? Or that new satellite dish? Solar panels you just installed? Is that bridge really the height the sign claims?
Nothing will ruin your day faster than the instant you realized that your RV was too tall to fit below the bridge you just went under. Understand that every state is different as to whether they mark the height of bridges or not, or whether that sign posted is accurate. But here again, each state may be different. The Federal Highway Administration sets bridge clearances at feet, unless a special design exception is obtained.
There is no Federal maximum height regulation on commercial motor vehicles. However, remember that states have their own restrictions. The vertical clerance of a bridge is the minimum height between the pavement and the bottom of the overhead structure. The weight limit refers to the maximum gross and axle weights for trucks.

Most states allow a maximum legal height of 13 ft, 6 in. The problem is that a load that is just a few inches higher than the maximum legal height may become a superload in terms of planning and costs.
Each state requires permits for overdimensional loads. But this is just the beginning. The cost of the actual permit is relatively low compared to the expenses of route surveys and other expenses associated with safely transporting an overheight load. State fee for the permit to haul the load. Permits can vary widely in price depending on the actual height and varies significantly from state to state. In addition to the permit, states are likely to charge a preparation fee for the time it takes to review the routes, collect all the route and haul information and prepare the permit.
This requires traveling the entire route and identifying and measuring every overhead obstacle along the route, including bridges and overpasses, signs, traffic and railroad signals, overhead wires, and even tree limbs.
A route surveys can cost up to several dollars per mile. Surveys are usually priced on a per-mile basis, but the rate may change from simple oversize loads to super-loads. Coordination with Utilities: On a haul of several hundred miles, there are likely to numerous utilities involved, including multiple power and telephone companies. Expenses for ensuring no damage to these utilities varies widely, from relatively low flat rate fees, to higher fees for multiple service trucks and teams of technicians.
