Removing a load zone may be requested if rehabilitation or reconstruction has been performed, or the load-zoned road can carry the traffic until the next scheduled rehabilitation without premature failure. If the highway was upgraded by using an approved design process that accounts for future projected traffic, then no further analysis is necessary and recommendation for removal of restrictions shall be made by Executive Order. However, if an upgrade was accomplished by means of a maintenance effort (or 2R program), then the district must perform a deflection survey of the upgraded highway using the

setup on the falling weight deflectometer (FWD).

Refer to the step-by-step instructions in “Table 13-1: Changing Load Zones on Roads” for removing a load zone.
