Construction of the Trans-Alaska Pipeline System first load of oil from the Trans-Alaska Pipeline System. When the TAPS group initially proposed the pipeline in 1969, the proposed cost was $900 million, and the pipeline would be completed by 1972. By January 1970, the projected cost had risen from $900 million to $2 billion. In October 1973, Alyeska further refined its figures and anticipated a cost of between $3.1 billion and $3.5 billion, with the potential for a billion more.
