San Francisco Factoid - BART Transbay tube

== The San Francisco Factoid ==
Essential local trivia you'll probably forget almost immediately

BART's landmark transbay tube was completed in August, 1969. Constructed in 57 sections and reposing on the bay floor as deep as 135 feet beneath the surface, the $180 million structure took six years of seismic studies to design, and less than three years to contract. Before it was closed to visitors for electrification, thousands of adventurous folks had walked, jogged, and bicycled through the tube. It received a dozen major engineering awards and rapidly became famous, seeming to capture the imagination of visitors from all over the world.
