For example, if the highway section requires substantial speed reduction due to vertical or horizontal alignment, and roadway approach to the bridge requires only a very minor additional speed reduction at the bridge, the appropriate code would be a 6. This concept shall be used at each bridge site. Speed reductions necessary because of structure width and not alignment shall not be considered in evaluating this item. Code Description N Not Applicable (Conveyor, Pedestrian, Railroad) 9 Condition superior to present desirable criteria 8 Condition to present desirable criteria 7 Condition better than present minimum criteria 6 Condition equal to present minimum criteria 5 Condition somewhat better than minimum adequacy to tolerate being left in place as is 4 Condition meeting minimum tolerable limits to be left in place as is 3 Basically intolerable condition requiring high priority of repair 2 Basically intolerable condition requiring high priority of replacement 0 Immediate replacement necessary to put back in service ITEM #90 - PROPOSED IMPROVEMENTS If there are no proposed improvements planned for the bridge leave the entire item blank. You must code all or none of the item. Type of Work [2 digits] The information to be coded for this item will be the type of work proposed to be accomplished at the site to provide the service needed. It be coded for all structures that are eligible for HBRRP funds. (80% or less sufficiency, Structurally Deficient or Functionally Obsolete and > 20 feet clear span) It also may be coded for other structures. Code Description 31 Replacement of bridge or other structure because of substandard load carrying capacity or substandard bridge roadway geometry. 32 Replacement of bridge or other structure because of relocation of road. 33 Widening of existing bridge or major structure without deck rehabilitation or replacement includes culvert lengthening.
