The system is also built to withstand the immense stresses of Alaska's earthquakes, a testament to the sophisticated engineering that ensures its stability and longevity. Oil taxes and royalties flowing from the pipeline fund a significant portion of the state's budget, supporting public services like education, infrastructure, and healthcare without the need for a state income tax.
Since its groundbreaking in 1974 and subsequent completion in 1977, it has transported over 18 billion barrels of oil, fundamentally shaping the economic and environmental trajectory of Alaska and the nation. The solution required a massive infrastructure project to traverse three mountain ranges, over 800 rivers and streams, and the seismic activity of the Denali Fault.
