Florida Coast to Coast (C2C)
In 2014 Florida State Legislature approved a $50 million fund to complete gaps between trails across Florida. Across nine counties, 250 miles, this project connects the two coasts in a complete bike trail. This trail is not yet complete as of Nov 2019, but construction and planning are still underway.
