Special Instructions - Multi-Lane Highways

1. For multilane undivided highways (3 or more lanes). The rater shall evaluate the most distressed lane, generally the outside lane in each direction. Each direction of travel (each lane) shall total 50 percent of the section. You will not rate all lanes, as in past surveys.

2. For divided highways, each direction of travel shall be rated as a separate section. The rater shall evaluate the most distressed lane, generally the outside lane, in each direction. Each direction of travel shall total 100 percent (10).

3. When conducting the Condition Survey on divided, multilane highways, the condition of lanes in opposite directions of travel may not have the same rating. For example, there may be reflective cracking in one direction and no cracking at all in the other direction.

4. For divided highways, the ADT for each direction shall be the total (two-way) ADT for the highway.

5. Both directions of travel must be mileposted in the same manner. This means that all descriptions and milepost numbers will be identical for each direction.

6. There are instances where a two-lane primary route will split and become a four-lane divided facility at an interchange. For these cases, unless the divided section is at least 0.50 miles long, it shall be treated like a two-lane highway with only the outside lane in each direction being rated. For this case only, any paved shoulder would be ignored. If it is equal to or longer than 0.50 miles, then a new section shall be written up.

7. Interchange ramps are not to be rated.

8. If paved shoulders are on the outside lane, then record paved shoulder width only, do not include any width for the unpaved shoulder, even though it is present.

9. Mark the proper pavement width and number of lanes for each direction, not both directions (as is usually indicated on the printout).
