FDOT District 2:
Bridge Repair

Throughout Northeast Florida

American is responsible for the preparation of repair plans for numerous bridges throughout District 2. Repair plans have included the following:

James T. Butler Bridge and Amelia Island Bridge, Jacksonville: Replacement of the concrete fender system with a new fender system using plastic piles and whalers to provide a higher level of durability and energy absorption capability. A comprehensive investigation into the advantages and disadvantages of each type of system was conducted to determine the fender system that would provide the most value to the District. Repairs to the impacted fender system of the Acosta Bridge were also completed including the replacement of several piles and whalers as well as the catwalk.

Hart Bridge, Jacksonville: Rehabilitation, repair and painting of the bridge, which included a three-span continuous truss having span lengths of 748 feet, 1088 feet and 748 feet. A complete finite-element model of the bridge was developed to identify areas in need of repair due to corrosion and section loss in the steel members. Repairs were designed to strengthen the bottom and top cords of the truss as well as several diagonals. Repair details were developed for numerous connections throughout the length of the truss as well as to bearing plates and expansion joints. A complete load rating of the entire truss span was prepared.

San Pablo River (Intercoastal Waterway) Bridge, Jacksonville: Complete removal and replacement of existing fender system, catwalk, access ladders, deck boards, electrical system, navigation lights and signs for the 2,350 foot long bridge over San Pablo River (Intercoastal Waterway) Bridge on SR 10. Project includes an analysis of ship impacts and determination of the most suitable replacement fender type.
Sisters Creek Double Leaf Bascule Bridge, Jacksonville: Rehabilitation, repair and painting including the installation of impressed current cathotic protection systems and galvanic pile jackets, replacement of the railings, and repairs to the areas of the structural system where section loss has advanced to the state where higher than allowable stresses are being experienced. Repairs included the replacement of corroded seat angles for stringers, rehabilitation due to shear cracks in the webs of some stingers, bearing replacements and strengthening of main girder flanges where they had been impacted. The entire steel superstructure will be cleaned and repainted.

I-95/Myrtle Avenue Bridge, Jacksonville: Rehabilitation of I-95 over Myrtle Avenue, including the removal and replacement of the drainage trough servicing the finger joints at piers 10 & 13, removal of the longitudinal drainage trough over the railroad and extending the scuppers, and replacement of the median longitudinal joint in the approach spans. A complete load rating of this seventeen span bridge having a total length of 1430’-7” with a center tied arch span having a length of 385’-6” was completed.

Crescent Beach Bridge, Jacksonville: Rehabilitation, repair and painting of the SR 206 bridge over the Matanzas River. Rehabilitation includes the complete cleaning and repainting of all of the structural steel, bearings, open steel grating, steel plates, anchor bolts and nuts. A complete analysis and load rating was conducted of the 2980 foot long structure including the bascule leafs to determine if corrosion would negatively affect the performance of the bridge.
