With the installation of the new steel girders nearing completion, placement of the forms for the new deck is now underway. These forms are built up of corrugated metal sheets used to form the bottom surface of the new concrete deck. The galvanized sheet metal spans between the bridge girders and supports the weight of the wet concrete until it hardens and gains strength. These forms are intended to remain after the concrete hardens, but do not provide any long term strength to the structure. Instead, they are left in place to serve as a means of sacrificial protection from corrosion.

This view is of the fiberglass pipe piles that have been driven adjacent to the navigation channel for the new bridge's fender system, along with the horizontal plastic lumber elements. The fender system serves primarily as a navigational aid for vessel traffic by delineating the designated channel beneath the bridge. It is also designed to be robust enough to withstand an impact from an errant vessel, thereby protecting the concrete piers which support the bridge structure in the event of a vessel strike. The fenders installed for the new bridge were built to receive a connection from the rehabilitated bridge to provide a single, continuous method of protection.

This photo is taken just west of the East Thorofare bridge crossing (the eastern most bridge within the project limits). This shows the newly installed steel sheetpile bulkhead and its concrete cap on the right side of the photo. This bulkhead was installed at the southwest corner of this bridge where some advanced deterioration was observed on the original timber bulkhead. The new bulkhead is designed to withstand scour and support the slopes required to maintain the recently installed landscaping elements.

This photo shows one of the two timber pavilions built within the environmental mitigation/restoration limits of Cedar Bonnet Island. This portion of the project is focused on protecting the environmental resources in the coastal area, improving wildlife habitat, and providing improvements to public access. This recreational area is scheduled to open to the public in late Spring of 2018.
