Construction History  Design Elements

The new design is dynamic and functional. It will have two 240 foot high towers / pylons on each side of the bridge with single plane cable stays. For comparison, Williams V. Roth Jr. Bridge over the Chesapeake & Delaware Canal has two 180 foot towers / pylons and a single plane of cable stays down the center of the bridge. The current Indian River Inlet Bridge has support piers in the inlet and no supporting towers.

The new bridge will also be 2,600 feet long, including a 900 foot clear span over the inlet, with 1,700 feet of bridge decking over the land. All supports will be out of the water, eliminating the conditions that now exist with the existing bridge. The new bridge will have a minimum 100-year design life. The foundations will be supported on 36 inch-square piles, which will be manufactured by Bayshore Concrete Products, a subsidiary of Skanska Southeast. Skanska had previously used these types of piles on the Escambia Bay I-10 Bridges in Florida.

Under the new design, the minimum vertical clearance will increase from the existing 35 feet to 45 feet over the navigational portion of the inlet. The bridge will have two 12-foot wide travel lanes, a 10-foot wide outside shoulder, and a 4-foot wide inside shoulder in each direction. Additionally, one 12-foot wide sidewalk will be accessed from the east side of the bridge. The reduced embankment limits will result in the elimination of massive embankments and will provide an open view.
