Abstract

The Defense Bridge Log is prepared for the purpose of compliance with policy and procedure memorandum 50-6.l dated November 14, 1972, and is submitted annually to the Federal Highway Administration. The log is provided to fulfill requirements of the Department of Defense and in order that the Federal Highway Administration may have sufficient data to complete its national emergency and disaster relief requirements. The source of data used to prepare this report is the Highway Commission's Planning Division Structure Base Record Inventory System and Description File. This data is collected by inventory crews and is updated annually to reflect changes to the structures on the Primary Road System.
