What were the proposed solutions for transporting oil from the isolated north in Alaska to the market?

I- Icebreaker tankers that would travel through the frozen Arctic seas to the Atlantic were seriously considered.
II- A monorail or a fleet of trucks in permanent circulation on an eight-lane highway across Alaska were suggested.
III- A fleet of nuclear-powered submarine tankers that would travel under the polar ice cap to a deep-water port in Greenland was recommended.
IV- Boeing and Lockheed explored the idea of jumbo jet oil tankers.
V- It was decided to build a pipeline, but there were two proposals: an eight-hundred-mile pipeline south from the oil fields to the port of Valdez, and an entirely overland pipeline, east through Alaska to Canada, then south into the United States, eventually terminating perhaps in Chicago.
