Demolition and Repairs Underway for Pensacola Bay Bridge Following Hurricane Sally

Introduction

The Pensacola Bay Bridge, commonly referred to as the Three-Mile Bridge, has been a vital artery for transportation in Florida. However, following the devastating impact of Hurricane Sally on September 17, the bridge has faced significant structural damage, leading to its closure. As of September 28, the Florida Department of Transportation (FDOT) has initiated demolition efforts to address the damage and pave the way for repairs.

Assessment of Damage

In the wake of Hurricane Sally, the FDOT has been diligently inspecting the bridge to assess the extent of the damage. The inspection process is nearing completion, with thorough surveys of the piers and topside inspections already conducted. Additionally, divers have been working to evaluate the underwater footings, which are crucial for the bridge’s stability. To date, FDOT divers have inspected 202 underwater footings, while topside teams have assessed 105 spans, 202 piers, and 525 beams.

Demolition Efforts

The demolition phase focuses on clearing specific areas of the bridge to allow divers access to the final 22 footings located below the waterline. This meticulous process is being expedited through the use of additional resources, including three contractor-operated barges that remain on or under the structure. The removal of these barges is a delicate operation, as it must be executed with caution to prevent further damage to the bridge. The contractor is prioritizing this task and is collaborating closely with FDOT to ensure minimal disruption.

Designing Permanent Repairs

As demolition progresses, the design for permanent repairs is already underway. The goal is to restore the bridge to its full capacity, reestablishing four lanes of traffic while ensuring the structure’s durability and strength. FDOT emphasizes that the repairs must not compromise the bridge’s integrity. The contractor has already fabricated 25 beams and piers necessary for the repairs and is actively constructing additional components at an offsite yard. This proactive approach aims to facilitate a swift installation process once demolition is complete.

Preliminary Inspection Findings

The preliminary findings from the inspections indicate that five spans will require full replacement, with an additional two spans needing partial replacement. While the exact number of beams that need replacement is still being determined, FDOT is committed to addressing all structural concerns comprehensively.

Traffic Impact and Detour Routes

Due to the ongoing repairs and demolition, the Pensacola Bay Bridge will remain closed until further notice. Motorists are advised to utilize alternative routes, including the Garcon Point Bridge and State Road 87. To alleviate some of the financial burden on commuters, tolls on the Garcon Point Bridge have been suspended until 6 a.m. on October 23. For detailed information regarding detour routes, including graphics and FAQs, the FDOT website serves as a valuable resource.

Conclusion

The ongoing efforts to demolish and repair the Pensacola Bay Bridge highlight the resilience and commitment of the FDOT and its contractors in restoring this essential infrastructure. As the community awaits the completion of these repairs, the focus remains on ensuring safety, durability, and minimal disruption to traffic. Regular updates will be provided to keep the public informed about the progress and any changes to detour routes.
