For 96 years, the Carquinez Straits crossing supplied power to the San Francisco Bay Area under severe environmental conditions. It was an extremely reliable crossing and stands as a tribute to the engineers and the construction and maintenance workers who designed, installed, and maintained it over the years. PG&E saved and donated a set of the 1914 pyramid-style insulators to the Northwest Lineman College, and they are now on display at the Oroville, California, campus (see Figure 17). Students and visitors to the college are able to view the last tangible reminder of one of the most significant engineering and construction accomplishments in the history of electric power transmission.
