The Road to Cayo Santa María is a road that was planned to go from the Abel Santamaría Airport to Cayo Santa María in order to get tourist from the airport to the hotels faster and safer.

The Causeway finished paving all 48 km in 2000, becoming the longest Courseway in the world and has been awarded the Puente de Alcántara prize for the "Best Ibero-American Civil Works", for its size, structure, and engineering in an area of great economic potential and its integration into the natural landscape.

[1] In 2020, Mintur, made an observation on the causeway, with it needing the readjustment of the metal road protection curbs, along more than 40km, and the repair of several connecting bridges of the viaduct.

The biggest hit on the road was Hurricane Irma in 2017, causing increasing displacement of the internal components of the structure.

[3] The plan was supposed to be revived in 2011, with 15 km already built beforehand, they just needed the final touches for it to get approved for the economy of next year,[4] although the road is currently only under construction in the eastern intersection with the Circuito Norte, and nothing appears to be done in the west.
