Until the 1700s, Arkhangelsk was the main trading harbour for the sea trade of Russia and Western Europe, and the Sukhona was on the main trading route connecting the central Russia with Arkhangelsk. Peter the Great drastically changed the situation, by founding Saint-Petersburg in 1703, thus opening the way for the Baltic Sea trade, and by constructing the highway between Saint-Petersburg and Arkhangelsk via Kargopol. The river quickly lost its role as the leading trading route, which was accelerated by the construction of the railway between Vologda and Arkhangelsk between 1894 and 1897.
