The Sanibel Causeway is a causeway in Southwest Florida that spans the San Carlos Bay, connecting Sanibel Island with the Florida mainland in Punta Rassa. The causeway consists of three separate two-lane bridge spans, and two man-made causeway islands between them. 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, and currently has a $6 toll in effect for island-bound vehicles only. The bridges are not individually named, and are simply referred to as bridges A, B, and C.HistoryAs early as 1912, automobile ferries serviced Sanibel Island from the mainland at Punta Rassa. The idea of building a bridge from the mainland to the island was highly controversial amongst the early residents of the island, as many thought a bridge would ruin the beauty and isolated feel of the island. Although, one of the largest proponents of building a bridge was island resident Hugo Lindgren who saw the island's potential and tried to convince Lee County to build a bridge. Despite the opinions of the islanders, it was clear that the ferries were insufficient by the mid 1950s as demand increased leading to long lines of vehicles waiting to cross the bay. Wildfires on the island in 1955 further convinced the county to build a bridge as it would improve access to the island for firefighters.An early proposal would have had a bridge running from Point Ybel (where Sanibel Lighthouse is currently located) to the mainland, since it was the shortest route. Although the current route was ultimately selected due to the bay being shallower and two causeway island could be created by dredging. While Bailey Road was then selected as the terminus of the bridge on the island, Hugo Lindgren granted the county right-of-way through his property on the bay, which the county accepted.
