These bays connect with the funnel-shaped opening to the Barents Sea via a narrow strait called "Gorlo" (, meaning "throat"). Kandalaksha Gulf lies in the western part of the White Sea; it is the deepest part of the sea, reaching 340 metres (1,115 feet). On the south, Onega Bay receives the Onega River. To the southeast, the Dvina Bay receives the Northern Dvina River at the major port of Arkhangelsk. On the east side of the 'gorlo', opposite the Kola Peninsula, is

They are used for cargo traffic though. In 1765, a road was built between Saint-Petersburg and Arkhangelsk, mainly for postal service. The road still exists and passes Kargopol and Plesetsk, and it has been paved in 2011. One of the principal highways in Russia, M8, connects Moscow and Arkhangelsk,
