Had to go back to the bridge!
The sun was up in full glory. Drove back an hour to the bridge to see how the waters looked in the sunlight. This time, I climbed up a nearby limestone outgrowth and took the shot. You can see the bridge and you can see how different the waters look on the Atlantic Ocean side and the Caribbean Sea side. It is an incredible view – almost jarring to watch from the bridge how two endless bodies of water are simultaneously very different colors while being in contact with each other!
