The Trans-Alaska Pipeline at 50 — what we’ve learned and what comes next

By Philip Wight

Fifty years ago, Alaska experienced the biggest man-made earthquake in our history. The ground shook as heavy machinery forged a new road to the Arctic Ocean, hundreds of thousands of new people flooded into the state and tens of thousands of workers built an unprecedented pipeline system.

In the words of former Gov. Jay Hammond, Alaskans experienced a “maelstrom of change.” The construction of the Trans-Alaska Pipeline System (TAPS) emerged as one of the biggest infrastructure projects of the 20th Century and one of the most consequential events in Alaska’s history.

Between 2024 and 2027, Alaskans have a unique opportunity to reflect on 50 years of our most famous megaproject (constructed between 1974-1977), how it changed the nature and character of Alaska, and what lessons it holds for our collective future.

The pipeline project thoroughly remade Alaska — perhaps only World War II proved more transformative. TAPS was not simply a physical infrastructure that moved and monetized Arctic oil; it also constituted a turbulent historical process. The advent of TAPS created nothing less than a “new social order”, according to journalist James Roscow.

The controversy over constructing TAPS expedited and influenced the character of the Alaska Native Claims Settlement Act (ANCSA), a historic piece of legislation which has had expansive social and economic effects. The pipeline boom nearly doubled Alaska’s population and changed the character and politics of those who lived here. This boom remade the physical environment — not only with a new highway to the Arctic Ocean and an 800-mile silver ribbon of steel, but also in the form of new skyscrapers in Anchorage and more than half of all homes built in Alaska. It brought tremendous new wealth, transforming Alaska from one of the poorest to one of the richest states in the nation.

The advent of TAPS also mobilized Alaskans to save some of their oil wealth and invest in renewable resources. Alaskans reacted to the turmoil of the pipeline boom in 1974 by electing a Republican conservationist (that rarest of endangered species) named Jay Hammond to the highest office in the Great Land. Under Hammond’s leadership, Alaskans created the Permanent Fund — the single most important development of Alaska’s oil age — and worked to invest one-time oil dollars into renewable resource projects, from fisheries to hydropower to agriculture. Yet Alaskan politicians (including Hammond, to his great regret) also voted to eliminate the income tax and allow government to be almost singularly dependent on a single resource flowing through a single pipeline.

The realization of TAPS contributed to hundreds of billions of dollars of wealth for the state, but it also resulted in the worst environmental disaster in Alaska’s history — the Exxon Valdez oil spill. Alaskans continue to live with this dual legacy of wealth and pollution.

The vast scale and historical influence of TAPS presents a challenge to Alaskans: How do we reckon with the most important economic infrastructure in Alaska’s history? How should we judge the successes and failures of a system that is still operating and likely will be for decades to come? How do we as a state and a society learn the crucial lessons from the pipeline system’s past as we chart a more sustainable future?

Fortunately, Alaskans from all backgrounds have begun to reflect on the 50th Anniversary of TAPS. The advent of the pipeline meant very different things to different groups.

Between Sept. 24 and 27, the Alaska Historical Society (AHS) will be discussing the 50th anniversary of TAPS at its annual meeting at the University of Alaska Fairbanks. The conference features a keynote address from former Gov. Bill Walker and multiple panels discussing the construction and maintenance of TAPS.

Those who labored to build the pipeline have been especially active in commemorating the three-year frenetic construction of the megaproject. Starting last year, the Alaska Oil and Gas Historical Society (AKOGHS) has organized pop-up exhibits on the construction of the Haul Road and the first pipe installation at Tonsina. On Oct. 2, the group is organizing an event in Fairbanks on the anniversary of the completion of the Yukon River Bridge. AKOGHS has also been recording valuable oral histories of individuals who worked on TAPS.

The next day, Oct. 3, the Alaska Bar Association will convene an Anchorage lunch discussion entitled, “The Taproot: Perspectives on the Pipeline in Alaska Legal History” with Alaska Supreme Court Justice Warren Matthews, James Reeves, and ANCSA-architect Willie Iggiagruk Hensley.

The Alyeska Pipeline Service Company, the operator of TAPS and agent of its owner companies (Hilcorp, ConocoPhillips, ExxonMobil), has been gearing up to commemorate its historical highlight — the 50th anniversary of “oil in” in June 2027.

These events, and hopefully many others, will help Alaskans understand our shared past, present world, and future challenges. TAPS offers important lessons for Arctic development, national environmental policies, oil tanker regulations, Alaska’s political history, the structure of the proposed Alaska natural gas pipeline project (AK LNG), and how the U.S. can once again build big things. TAPS has impacted nearly every corner of Alaska. Reflecting on its history and future is a project beyond any one company or industry. It’s a timely project for all Alaskans.
