Transcontinental Telegraph

The telegraph and Morse code invention made it possible to quickly transmit information over long distances. There were Russian, European and American construction projects of telegraph lines. In the 1860s and 70s, a domestic project was carried out to build the St. Petersburg - Siberian Cities – Alexandrovka line in the Far East. Russia and the USA jointly designed a highway through Beringia. In fact, an underwater cable line has been implemented from the Primorsky coast to Nagasaki in Japan, then to Hong Kong and across the Indian Ocean, the Red and Mediterranean Seas to London, with a continuation across the Atlantic Ocean to the USA and overland to St. Petersburg. A huge electric circle was formed, encircling the world space, which became the scientific and technical basis of the information revolution of the second half of the 19th century
