The Coalinga-Monterey pipeline was built during the early 20th century but only operated for a few years and then abandoned. Parts of it still exist but are no longer being used to transport oil from the petroleum-rich Great Central Valley to the picturesque Central Coast.

Transportation of oil from the Coalinga Oil Fields in Fresno County to the port and City of Monterey began October 24, 1904. The independent "Coalinga Oil and Transport Company" was purchased in July 1905 by Associated Oil.
The pipeline operated until the Great Fire of Monterey on September 14, 1924. The cause of the fire was from a 55,000 gallon Associated Oil storage tank on the Monterey Wharf which had been struck by lightning during an intense late summer storm. The fire threatened the City of Monterey and was not under control until the following day.
