The causeway consists of three separate two-lane bridge spans, and two man-made causeway islands, which are located between each of the three bridges. The entire causeway facility is owned by Lee County and operated by the Lee County Department of Transportation. The entire causeway is three miles long from end to end.
The project consisted of the replacement of two fixed bridges and one bascule bridge over the Caloosahatchee water way. These bridges connect Lee County mainland with Sanibel Island. In addition, Allied (now Volkert, Inc.) provided construction materials testing and inspections. These consisted of pile (driven, Augercast and sheet piles) monitoring, turbidity monitoring, vibration and noise monitoring, soils, concrete and asphalt testing and MSE wall inspection. In addition, Allied (now Volkert, Inc.) provided underwater video of the clean up in accordance with the US Coast Guard permit requirements.
