Bridge Information Reports
ALDOT's Bridge Information Reports on the Whatley Bridge (BIN-542) and the Mentone Bridge (BIN-543) both reflect a downgrading of Item-60-Substructure to 5 (fair). This single change reduces a Bridge Sufficiency Rating by 10%, according to the Recording and Coding Guide for the Structure Inventory and Appraisal of the Nation's Bridges.
The Bridge Sufficiency Ratings prior to the downgrade were greater than 50%. After the downgrade, they were less than 50%, resulting in eligibility for replacement funding under the following Federal Highway Administration Policy:
2 b. Federal regulations originating in Section 123(e) of the 1987 STURAA, also permits States to carry out bridge improvements on non-controversial off-system bridges (on local roads and rural minor collectors) without Federal funding, and then apply 80 percent of the cost of such projects as credit toward the non-Federal share of other HBRRP projects. The FHWA has developed basic national guidelines for uniform administering those projects and the guidelines are:
The Sufficiency Rating for the Whatley Bridge was decreased from 57.3 to 46.8 and the rating for the Mentone Bridge was decreased from 52.8 to 43.8 as a result of the extraordinary bridge inspections on August 4th, 2004. A comparison of items in the current Bridge Information Report on the Whatley Bridge (BIN-542) with the corresponding items in the current report on the Mentone Bridge (BIN-543) shows that the differences between the individual items do not correlate with the differences between ALDOT's calculations of the Bridge Sufficiency Ratings for the two bridges.
