About this file
This document is a Bridge Inspection Report for the Merchant Creek Bridge on the Natchez Trace Parkway. The report provides a detailed inspection of the bridge's condition, including an assessment of the deck, superstructure, substructure, and channel. It also includes recommendations for maintenance, rehabilitation, and reconstruction work, along with preliminary cost estimates.
The report notes the bridge is generally in good condition, with a few deficiencies that require attention, such as erosion around the piers, missing expansion joint material, and cracking in the railings and wearing surface. The report recommends repairs to address these issues, with an estimated rehabilitation/reconstruction cost of approximately $58,000. The bridge has an operating rating that meets or exceeds the design load capacity. No critical deficiencies were found.
