This is a super picture, from Wikipedia, of the San Francisco Bay Bridge that connects Oakland to East Bay.

Of course, no visit to this city is complete without a ride on the famous cable cars of Nob Hill.

The BART (Bay Area Rapid Transit) began regular passenger service in 1972, reporting more than 100,000 passengers in its first 5 days.

The Transbay Tube opened 2 years later (1974), thus linking each of the four branches extending to Daly City, Concord, Richmond, and Fremont.

The 1989 Loma Prieta earthquake gave BART an unequalled opportunity to shine as a star and major hero during this catastrophe.

Transportation between San Francisco and Oakland was drastically affected with the breakage of the bridge and the near total destruction of the Cypress Street Viaduct. Within six hours of the original earthquake, BART trains were operational, effectively becoming the sole mode of transportation throughout the area.

Kudos!
