My photos are FREE to use, just give me credit and it would be nice if you let me know, thanks.The Yerba Buena lighthouse connection began in 1873 when the Lighthouse Service moved the district's depot from Mare Island to the southeast side of Yerba Buena Island. In 1875 construction was completed on the 25-foot (7.6 m) tower with a fifth order Fresnel lens. In 1886 another fifth order lens replaced the previous one. In 1933, a tunnel was bored through Yerba Buena Island to serve as a link between the east and west sections of the Oakland Bay Bridge. The light was automated by the United States Coast Guard in 1958.Another lighthouse for my book.www.blurb.com/b/6537099-eastern-canadian-lighthouses-and-... |
