Engineering & EnergyMajor Design Changes
Incorporation of an alternate superstructure design of PrestressedI-Girders and associated substructure modifications.
Elimination of about 1800 feet of bridge structure over Rainbow Island by lowering the profile at the island and replacing it with a roadway section.
Elimination of the ramps that provide access to the fishing piers and parking lot at Rainbow Island; therefore, eliminating complex variable geometry of the bridge.
Shifting of the horizontal alignment slightly over Rainbow Island.
