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. One year later, Alyeska released its most detailed cost estimate to that point: $5.982 billion. By June 1975, that figure had again risen to $6.4 billion. At
Central Asia–Center gas pipeline system proposed to renovate existing systems and construct a new parallel pipeline to the western branch. On 12 May 2007, Vladimir Putin of Russia, Nursultan Nazarbayev of Kazakhstan and Gurbanguly Berdimuhamedow of Turkmenistan signed a memorandum for renovation and expansion of the western branch of the pipeline.
