Question: How long is the causeway that connects Fiesta Key to the mainland?
Context: 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. The two-mile-long Queen Isabella Causeway, located in southern Cameron County, Texas, is the only road connecting South Padre Island, Texas to the mainland.  The Causeway was opened in 1974 and replaced the previous bridge, which had also been named Queen Isabella Causeway.  A central section of the original causeway has been removed and it has been renamed the Queen Isabella State Fishing Pier.  The Causeway is the second-longest bridge in Texas, stretching 2.37 miles (3.81 km) across the Laguna Madre The John B. Whealton Memorial Causeway, more commonly known to the locals as the Chincoteague Causeway, connects the mainland of the Eastern Shore to Chincoteague, where it continues into town as Maddox Boulevard.  The causeway is part of State Route 175 (Chincoteague Road).  The causeway contains five bridges and crosses the following (west to east): The Hindenburgdamm or Hindenburg Dam is an 11 km-long causeway joining the North Frisian island of Sylt to mainland Schleswig-Holstein.  Its coordinates are .  It was opened on 1 June 1927 and is exclusively a railway corridor.  The companies that built the Hindenburgdamm, a job that took four years, were Philipp Holzmann AG of Frankfurt, working from the mainland, and Peter Fix Söhne of Duisburg working from Sylt.  A train trip along the causeway takes about 10 minutes, and the time between the auto terminals at Niebüll on the mainland and Westerland on Sylt is about 30 minutes.  The Hindenburgdamm is part of the railway line known as the "Marschbahn" ("Marsh Railway"), which is double-tracked along much of the route, although there as yet exists a single-tracked stretch.  On the causeway is a signal box. The Overseas Highway is a 113 mi highway carrying U.S. Route 1 (US 1) through the Florida Keys.  Large parts of it were built on the former right-of-way of the Overseas Railroad, the Key West Extension of the Florida East Coast Railway.  Completed in 1912, the Overseas Railroad was heavily damaged and partially destroyed in the Labor Day Hurricane of 1935.  The Florida East Coast Railway was financially unable to rebuild the destroyed sections, so the roadbed and remaining bridges were sold to the state of Florida for $640,000. Bird Key is an island in Sarasota Bay, south of the Ringling Causeway, between mainland Sarasota and St. Armands Key.  Originally a small island connected to the Ringling Causeway by a tree lined causeway of its own, it was the home of John Ringling North, nephew of Circus Magnate, John Ringling.  Created by dredge and fill in the late 1950s, it is approximately 250 acre of one of the most prestigious residential areas on Florida's West Coast. Fiesta Key is an island in the Florida Keys, connected via causeway to U.S. 1 (or the Overseas Highway) at mile marker 70, between Long Key and Craig Key. Sion Causeway (also known as Duncan Causeway) is a major causeway in Bombay, India which connects Sion in Bombay with Kurla in Salsette.  The construction of the causeway began in 1798 and was completed in 1805 by Jonathan Duncan, Governor of Bombay (1795–1811), at a cost of £5,037 (Rs.  50,370).  In 1826, its breadth was doubled and improved at a further outlay of £4,000 (Rs. 40,000) A volcanic tract extends from Carnac Bunder to Sion Causeway, and forms the entire of the chain of hills bordering the north-eastenn end of the island from the Sewri Fort to Sion. The Great South Bay Bridge is a bridge on the southwest side of Suffolk County, New York, on Long Island.  It connects the Robert Moses Causeway from Long Island's mainland over the Great South Bay, connecting to both Captree and Jones Beach Island.  It serves as access via the Robert Moses Causeway to both of the downstream crossings, the State Boat Channel Bridge and the Fire Island Inlet Bridge, also leading visitors and on-lookers to either the Fire Island Lighthouse or the Robert Moses State Park.  It is the second longest bridge in the New York State, behind only the Tappan Zee Bridge. The Walter B. Elliott Causeway is a causeway built in 1973 that connects Twillingate Island with the rest of Newfoundland.  It is part of Route 340.  Prior to the causeway, residents used a ferry service to travel between Twillingate island and mainland Newfoundland.
