STRUCTURE EVALUATION SUMMARY

This triple barrel masonry culvert is in critically poor condition overall, and has some problems that require immediate attention. During the 2015 inspection cycle, the structure was found to be in very poor condition due to the partial collapse of two barrel walls and loss of back-fill material. The loss of fill material resulted in a large void behind the south end wall, causing undermining of the approach pavement. During the 2017 inspection it was found that local work force had placed a concrete slab, 12" thick, over the south approach. However, no plans or construction details for the installation were available. Due to heavy rains from hurricanes and high water levels, the inspection team was unable to inspect the underside of the structure at that time.

Due to drier conditions during the 2019 inspection, the inspection team was able to access the underside of the structure. It was found that the condition of the barrel walls, the south end wall, and the erosion cave due to loss of fill behind the south end wall had not been repaired.

The partial collapse of the south wall at the center barrel has an opening 10 feet long by 3.8 feet high. The south end wall has also partially collapsed, leaving an opening 13 feet long by 4 feet high. These conditions have resulted in a severe loss of fill material, which has left a large void (15 feet long by 10 feet high by 10 feet wide) directly under the traffic lanes. The loss of fill material has progressed since the previous inspection.

Since the previous inspection, temporary plastic barriers were placed along both sides to reduce the traffic to a single lane, along with lane restriction and "No Commercial Vehicles" signs. However, the temporary barriers were pushed to

the shoulders, allowing for for two-way traffic.

A structural analysis was performed on the reinforced concrete slab, based on the conditions observed during the inspection. Since no plans for the reinforced concrete slab were available, it was assumed that the concrete had a compressive strength of 4000 psi and the minimum required steel reinforcement. Based on these assumptions, the analysis showed a single axle capacity of less than two (2) tons.

In accordance with the AASHTO Manual for Bridge Evaluation, bridges not capable of carrying a minimum gross live load weight of three (3) tons must be closed. Therefore, due to the critical condition of the structure and in consideration of the results of this analysis, it is recommended that the bridge be closed. The slab repair does not have sufficient capacity to span the current conditions at the structure with the adequate factors of safety required.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 2902-020P

STX69910 INSPECTION DATE : 01/24/2022

PRIORITY OF IMPROVEMENT226

A (Critical) - Structure is closed, in immediate damage of collapse, or presents a critical safety danger.

B (Major) - Structure is seriously deficient or presents a safety hazard, but can remain open at reduced loads or with frequent inspections.

C (Moderate) - Structure is deficient, functionally obsolete, or requires substantial repairs to prevent a serious deficiency or unsafe condition.

D (Minor) - Structure is generally in good condition. Preventive maintenance may be required.

E (Special) - Structure is under construction or reconstruction.
