Siberian trakt

The Siberian Route (Russian: Сибирский тракт; Sibirsky trakt), also known as the Moscow Highway (Moskovsky trakt, Московский тракт) and Great Highway (Bolshoi trakt, Большой тракт), was a historic route that connected European Russia to Siberia and China.

The construction of the road was decreed by the Tsar two months after the conclusion of the Treaty of Nerchinsk, on 22 November 1689, but it did not start until 1730 and was not finished until the mid-19th century. Previously, Siberian transport had been mostly by river via Siberian River Routes. First Russian settlers arrived in Siberia by the Cherdyn river route which was superseded by the Babinov overland route in the late 1590s. The town of Verkhoturye in the Urals was the most eastern point of the Babinov Road.

The much longer Siberian route started in Moscow as the Vladimir Highway and passed through Murom, Kozmodemyansk, Kazan, Perm, Kungur, Yekaterinburg, Tyumen, Tobolsk, Tara, Kainsk, Tomsk, Yeniseysk and Irkutsk. After crossing Lake Baikal the road split near Verkhneudinsk. One branch continued east to Nerchinsk while the other went south to the border post of Kyakhta where it linked to camel caravans that crossed Mongolia to a Great Wall gate at Kalgan.
