FDOT response to St. Pete Times EditorialThe Florida Department of Transportation (FDOT) is responding to the editorial “Cracks in bridge dent confidence in FDOT” published August 28, 2008. The article did not accurately present the complete facts or the FDOT actions regarding the cracks that were reported. The bridge plans, inspection reports, and field observations were reviewed with construction and structural design engineers. This review confirmed the cracks did not represent any structural problems. If the cracks presented a public safety concern, they would have been addressed immediately. Public safety is always the most important priority of FDOT. We want the public to know the new Clearwater Memorial Causeway Bridge is completely safe. The cracks are in an area known as a concrete “closure pour.” The bridge consists of two separate structures with a gap intentionally built between them. While the two structures could have been safely left separate, this gap was closed by placing a layer of concrete between them. Since it only links the structures, the closure pour does not contribute to the structural integrity of the bridge. The cracks are not uncommon and primarily occur where concrete sections are poured at different times. FDOT inspectors and structural engineers routinely monitor and address the condition of the bridge, including any cracks discovered. The cracks are not “several inches” wide as reported but are a fraction of an inch. The staining makes the cracks look unsightly and larger than they actually are on the bridge. As FDOT had previously explained, the area where the cracks appear will be cleaned and repaired. As a preventative maintenance measure, we also plan to seal the concrete surfaces to prevent water from running through the cracks. To alleviate any confusion and public concern the editorial may have created, please inform the public the cracks will be repaired in the near future, well before any structural damage would ever occur. We understand your concerns regarding the challenges associated with the maintenance and operation of the old drawbridge and the construction of the new bridge. All new bridge construction issues were resolved satisfactorily thus ensuring the safety of the public. There should be no correlation between routine maintenance activities and the issues that took place during construction. In summary, FDOT dispatched staff and responded to the concern and determined the cracks represented no threat to the safety of the public. Required repairs will be made in a timely manner to insure the longevity of the structure. We appreciate your interest in transportation issues and remain at your service to assist you in informing the public of the facts. - Donald Skelton, P.E., Florida Department of Transportation, District Seven Secretary
