The committee began by selecting the “Concrete Arch” bridge type from four bridge type options: Conventional Concrete Beams, Enhanced Concrete Beams, Segmental Concrete, and Concrete Arch. Next, the committee chose which style of concrete arch designs they preferred. This preference then went into the BDR (Bridge Development Report) prepared by the Design Team. The BDR analyzed three of the alternatives, including the committee’s preferred alternative, based on factors and criteria including cost, maintenance, construction schedule, aesthetics, constructability, hydraulics, viewshed, and environmental impacts. These categories were all weighted and the bridge types were each given a score based on their performance. It was determined through this process that the open spandrel design was the best alternative out of the three to move forward with in the design process.

Bridge pier styles were also presented to the committee for their preference, and they decided on the flat front face with the rectangular shaped overlooks and coquina from the base of the pier to about half way up the pier. Other options presented for the pier style included the diamond shape and art deco. The alternate overlook options included a round/circle shape and a diamond/triangle shape. All of these alternate options were eliminated by the committee.
Fishing piers were discussed during the meetings as well and it was a commitment during the PD&E phase to have two fishing piers, one on the east side and one on the west side. These fishing piers were laid out according to the locations of the existing channels (new and old), accessibility, and right‐of‐way availability. Both fishing piers are located on the north side of the bridge. The pier on the western side will be an “L” shape and the pier on the eastern side will be a “T” shape. The material used on the fishing piers will be wood. Other options such as composite wood and concrete were discussed, but the option of wood was preferred. The fishing piers will be 10’ wide along the walkway and the end fishing areas will be 20’ wide. They will be ADA accessible.
The next major endeavor for the committee was to select their lighting preferences for the bridge. They were able to choose from many different lamp styles including the roadstar, urbanscape, leonis, domus, renaissance, metroscape and serenade. The metroscape lamp was favored by the committee for use across the bridge. Other lighting elements that were discussed included the light color and temperature. The light color and temperature that the committee preferred was the more amber colored. The next major endeavor for the committee was to select their lighting preferences for the bridge. They were able to choose from many different lamp styles including the roadstar, urbanscape, or leonis lights to keep the historic feeling of the bridge.
