During carrying out comprehensive survey at the construction site of the road connecting Mezmay village with the existing road Lagonaki plateau–Dakhovskaya village (Krasnodar region), satellite images from the Google Earth program having sufficiently high resolution were used, which made it possible to assess the risk and danger of karst processes at the pre-design stage. The purpose of the research is to make design decisions for the normal construction process in the territory with developing karst processes. The article clearly shows how the use of satellite imagery, laser scanning data and maps of the road construction site provides for identification of the most important components of geological environment and factors contributing to development and activation of karst processes. Using LIDAR scanning of the study area it was possible to “remove” the upper forest layer (cover) and expose the relief of the site, determining size, shape and number of karst manifestations. This allowed performing preliminary assessment of the mechanism of the karst process that formed numerous depressions. These landforms are primarily formed not by sinkholes, but by corrosionerosion processes. That is, the development of karst funnels on this section of the projected road does not fall under the “standard” methodology for assessing karst hazard described in the SP. The reconnaissance of the road route and the inspection of karst funnels on the spot fully confirmed the above assumption. Indeed, all studied depressions in limestones of the Jurassic age had a corrosion-erosion origin. Thus, on the basis of the conducted engineering survey and karstological studies, the conclusion is formulated that during the construction and reconstruction of the road anti-karst measures are not required. A set of anti-erosion measures and monitoring of the state of the road is required instead.
