ENGINEERING OBJECTS OF TRANSPORT INFRASTRUCTURE IN THE BELARUSIAN LANDS OF THE GRAND DUCHY OF LITHUANIA IN THE SECOND HALF OF THE 60S OF THE 18TH CENTURY (ON THE EXAMPLE OF THE VITEBSK, MSTISLAV PROVINCES AND ORSHAN COUNTY)

The aim of this work is to determine the features of the functioning of engineering facilities of the transport infrastructure in the Belarusian lands of the Grand Duchy of Lithuania in the second half of the 1760s using the example of the Vitebsk, Mstislav provinces and the Orsha county. Using the identified sources, the article examines the main approaches of the state authorities to the creation of an effective road system. An analysis of the state of special structures (cabins, ridge roads, bridges) that were used to overcome difficult sections and improve travel conditions was carried out. The technologies and materials used for the construction of these structures were determined. The features of collecting duties for their use were revealed. The results of the study can be used in the preparation of textbooks, lecture courses and general works on the history of Belarus in the second half of the 18th century.
