Alta Telegraph Company

The Alta Telegraph Company was a telegraph company which operated in the mid-19th century within the state of California prior to the construction of the Transcontinental Telegraph. It was incorporated in the early 1850s. Its first line was constructed during 1854, stretching from Sacramento to Marysville and extending up into the foothills of the adjacent Sierra Nevada mountains. In subsequent years, a line was constructed between Sacramento and Benicia. From Benicia, a branch line was extended to Vallejo and the US Navy yard at Mare Island.
