The project to replace the deck of the 6-lane, 5,900-ft, steel girder bridge with precast, post-tensioned, lightweight concrete panels was completed in 12 months with minimum disruption of traffic. The bridge was widened by 4 ft 2-1/2 in., and the median was narrowed and the safety walk removed to provide shoulders for disabled vehicles. The innovative design features that contributed to the success of the project include the maintenance-of-traffic program; precast, post-tensioned, lightweight concrete panels; protection systems for reinforcement and strand, the use of methyl methocrylate polymer concrete; and the overall practicality of the system given the limiting criteria for the project. At the precasting plant, extensive planning contributed to the successful and expeditious completion of work. On site, early comletion was achieved through detailed planning and with innovations such as work platforms that were hung from the bottom flanges of the girders and moved ahead daily; temporary steel gird decks to carry traffic; and the sequencing of work. Preparatory work was performed during the day to allow the major work to proceed rapidly at night. This enabled the contractor to set 1,026 panels in 129 nights. The contractor completed the work at a reduced cost more than 3 months ahead of schedule.
