The trip from Fort Myers to Sanibel involves three bridges (which were rebuilt in 2007)
connected by small manmade islands.
Once you reach the end of the Causeway bridge, and are on the island,
you'll be on Causeway Road until you get to Periwinkle Way
The Visitors' Center
is on this street.
After Periwinkle, the road continues as Lindgren Blvd
