Initial phases of the 8th Street Bridge rehab project consisted of an in-depth inspection of the structure to quantify areas of deterioration, re-create existing plans of the structure for load rating analysis, analyze existing concrete characteristics through coring and petrographic analysis, conduct historical research, and provide a summary of findings with recommendations. At over 100 years old, deterioration was prevalent throughout the structure. The most significant amounts of deterioration were located on the underside of the arches within the outer 10 ft on the north and south edges of the bridge. Reinforcement was exposed and showed 70% section loss. The bridge had experienced some significant deterioration.
