About this file
This document is a Bridge Inspection Report for the Irving Branch Bridge on the Natchez Trace Parkway. The report was prepared by the Federal Highway Administration Federal Lands Bridge Office and provides an assessment of the bridge's condition, a load rating analysis, and recommended maintenance and rehabilitation actions.
The key findings include the need to remove vegetation growth, place engineered riprap at the stream facing slopes, repair cracked and spalled concrete on the curbs and wearing surface, and seal transverse and diagonal cracks on the approaches. The report includes a cost estimate summary for the recommended maintenance and rehabilitation work, which is estimated to total approximately $X. The bridge is generally in good condition with a "D" priority for improvements.
