Transco Pipeline Turns 75 Years Old – Flows 16% of U.S. NatGas

When the Transcontinental Gas Pipe Line (Transco) was placed into service in 1950, it was hailed as the longest pipeline in the world and the largest single-project construction venture ever attempted. Today, Transco, now owned by Williams, transports about 16% of the natural gas consumed in the United States. More than a single pipeline, Transco is a network stretching nearly 10,000 miles, connecting South Texas to New York. It's hard to overstate the importance of this pipeline system to the country and to the Marcellus/Utica region. It carries an estimated 4.0 to 4.5 billion cubic feet (Bcf) of M-U molecules every day. We have written over 1,100 posts on MDN, either focusing on or prominently mentioning Transco (see our list of posts here). Williams recently published an article to commemorate Transco's 75th birthday.
