No, not really. Seven Mile Bridge is a stretch of highway over the water, so while the view of the ocean is one of the most spectacular vistas on any Florida Keys tour, there isn't really anywhere to stop your car and look around.
From one end of the Seven Mile Bridge to the other, it is about a ten-minute drive. However, you should feel free to take your time since, as any Florida Keys tour will tell you, the Seven Mile Bridge has some of the most beautiful views of the ocean anywhere in the Keys.
