* Only these items are used in the determination of the overall condition rating for that category ie. Deck, superstructure, substructure.

Other items should be rated and remarked on but NOT included in determining the overall category rating. Items enumerated using a C (ex C1) should be commented on but not rated. See the FHWA Coding Guide for further information as to what is included in condition rating.
