Another good day on eBay and we have some more amateur shots of the 20k ride, I've also included three Disney press photos of the ride under construction, so enjoy!
The first two photos were shot in 1974.
This photo was taken in 1985 from the Skyway ride.
Here's an overhead shot of the ride, you can see the layout of the track for the subs to follow and the building that housed the dark portion of the ride. Its interesting to note that this building shares a very similar footprint to the one that was contructed for the Ariel/Little Mermaid ride in the Fantasyland expansion. Check it out HERE.
