THE UNION WATERSPHERE:

• 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.
