This giant water tower in Union is not really a water tower, it’s a water sphere. What’s the difference you ask? Well a water sphere has a round ball-like top while a water tower is round and squat with a flat top, like a marshmallow. For a long time the Union watersphere was the world’s tallest, but about 15 years ago, one was built in California that was 10 feet taller. It’s a Union landmark, which stands proudly next to the GSP right at the Union Toll Plaza. Speaking of the Union toll plaza, it shares it’s own place in history. It was home to the first ever automated toll collection device. The Parkway even has a plaque commemorating this event, complete with the first quarter ever collected by an automated toll machine.
