Section R17-6-108 - Route Survey and Contingency Plan

A. To promote safe transport of oversize and overweight vehicles, combinations of vehicles, or vehicle and load combinations, the Department shall evaluate each class C special permit application to determine, on a case-by-case basis, to determine whether a potential traffic safety risk exists that may require a comprehensive traffic control route survey and contingency plan as a condition of permit approval. The Department's decision to require a comprehensive traffic control route survey and contingency plan shall be based on its consideration of:

1. Bridge capacities;

2. Load size and weight;

3. Pavement stress;

4. Road width, grade, and condition; and

5. Traffic dynamics of the proposed route.

B. If the Department determines that a potential traffic safety risk exists, a class C special permit applicant shall submit to the Class C Unit at the time of application, a route survey and contingency plan, which shall address all of the following items:

1. Identify all roadway features located along the proposed route that may inhibit movement of the vehicle, combination of vehicles, or vehicle and load combination;

2. Identify all obstructions that may be subject to potential disturbance or damage;

3. Specify how all structures, delineators, foliage, and official traffic control devices will be managed or avoided;

4. Specify all available pullout points located along the proposed route listed by highway and milepost number;

5. Specify how all side traffic will be managed;

6. Specify the rate of speed at which the load will travel along the proposed route;

7. Specify the approximate times during which the load is expected to be in transit;

8. Specify the plan to be followed in the event of a breakdown; and

9. Indicate the estimated time needed to change out a power unit or other special equipment if the Department, through detailed analysis and as a condition of permit approval, requires the use of an additional power unit or other special equipment to ensure safe transport of the proposed load. The Department's decision to require an additional power unit or other special equipment shall be based on its consideration of the:

a. Estimated timing involved with clearing a route after a breakdown;

b. Expected weather conditions;

c. Proximity and availability of reserve resources;

d. Size and weight of the load;

e. Traffic dynamics of the proposed route; and

f. Width, grade, and condition of the roads.

C. As a condition of class C special permit issuance, the Department may require an applicant to coordinate use of one or more law enforcement escorts as needed to ensure public safety while transporting a proposed load.
