Construction of Large Naval ships - Driving it onto land

So, let's say that through a series of strange timey wimey events, I accidentally jump-start several technological revolutions in the early 1800's. So, at any given time, technology is ~60 years ahead of where it should be, sans nuclear weapons (nuclear power does exist though). Now let's say that WWI and WWII don't happen. Now, let's also say that, in 1930, America is provoked into a short but bloody war, culminating in a months-long blockade and bombardment of the enemy's heavily fortified capital city. Beach landings are all but impossible, due to a series of anti-ship weapons under the water. The city can't perform an all out attack on the ships bombarding them, but they have supplies and weapons delivered to them from the land. The Americans can't get close enough to intercept the supply route, and this siege has been going on for months. In the port in Baltimore, the frame is being assembled for the largest ship ever built. "Super Dreadnought". 700 meters long, 3 nuclear reactors, and a retractable stabilization pylon on each side. Armaments:

10 31.5" guns
20 18" guns
20 16" guns
30 14" guns
40 3" AA guns
100 10" guns
300 .50 machine guns

It is decided that "nothing short of putting an entire battleship in the way could stop that damn supply route". Then an idea is pitched: put an actual battleship in the way. In particular, put the Super Dreadnought in the way. It's approved, and constructed with 7 sets of massive caterpillar tracks. Each set has one track directly under the ship, and one on either side. This massive ship is now amphibious.

Now, here are my questions:

1. Is my proposed method of making this ship amphibious plausible?
2. If so, what would the the approximate top speed?
3. If not, what can I change to make it plausible?
