About this file
This document is a Bridge Inspection Report for the MS Route 12 Bridge on the Natchez Trace Parkway in Mississippi. The bridge, Structure No. 5570-111P, was inspected on March 12, 2022 and found to be generally in good condition with a few deficiencies noted.
The report provides recommendations and estimated costs for maintenance, rehabilitation, and reconstruction work. Recommended maintenance items include sealing cracks in the wearing surface, cleaning and sealing exposed rebar, and repairing spalling on the exterior slab edges. The preliminary estimated cost for this work is $3,222. Rehabilitation and reconstruction work recommended within the next 5 years includes additional concrete repairs, with a preliminary estimated cost of $59,300. The bridge's load ratings meet or exceed the design load. No posting is required, though some overload vehicles have operating ratings below 1.0.
