About this file
This document is an engineering condition assessment and recommended repair plan for a bridge structure located on Norris Ferry Road in Shreveport, Louisiana, prepared by Owen Engineering, LLC on March 1, 2024. The plan details a single-span precast slab bridge structure over a tributary to Bayou Pierre, with comprehensive documentation of existing structural conditions including extensive erosion, damaged guardrails, decaying wood wing walls, and compromised abutments. The assessment includes detailed site photographs and technical diagrams highlighting specific areas of structural deterioration and recommended repair strategies.
The recommended repairs include multiple comprehensive interventions such as replacing guardrails on both sides of the structure, installing TL-3 MASH end treatments, filling and patching washout areas, adding stone rip-rap in high-velocity areas (approximately 120 square yards), replacing damaged concrete guard rail posts, and implementing stub pile reinforcements. The estimated repair scope involves structural elements like 20 linear feet of guardrail, wood spacers, concrete bent caps, and temporary support mechanisms. The document provides precise technical specifications for each recommended repair, including materials, dimensions, and placement strategies, with a focus on restoring the structural integrity and safety of the bridge crossing.
