Treasure Island Bridge, City of Treasure Island, Florida: E.C. Driver prepared a Project Development and Environment (PD&E) Study and prepared designs for replacement of three bridges on the Treasure Island Causeway over the Gulf Intracoastal Waterway in Pinellas County, Florida. The existing bridges are in a critical state of disrepair and are considered both structurally deficient and functionally obsolete. The existing bascule bridge crosses the waterway and provides only six feet of vertical clearance and 85 feet of horizontal clearance. The new causeway will consist of low-level fixed bridges on the east and west ends and a mid-level movable span bridge in the middle. In addition to engineering design and environmental documentation, ECDA processed permit applications, conducted a detailed public involvement plan and assisted the City with obtaining funding for the project. Between the East and West Bridges and spanning the main channel is the Bascule Bridge. The Bascule Bridge features a 240-foot bascule main span and twelve fixed approach spans for a total bridge length of 1,014 feet. The bridge provides twenty-one feet of vertical clearance in the closed position. In the open position the bridge provides unlimited vertical clearance over the full width of the 100-foot wide channel.
