The retaining wall is built on a slope with a height of 4.10 m and a length of 150 m. It "stands" on a foundation with a width of 2.50 m and a thickness of 1.00 m;
The foundation is secured with micropiles ф 75 with a length of 10.00 m, and IBO R 32 anchors with a length of 12.00 m pass through the retaining wall, anchoring the facility in the solid part of the slope;
The earth-rock massif above the wall is secured with a high-strength mesh, anchored to the slope with IBO R 32 anchors with a length of 6.00 m. An elastic barrier is installed on the left side of the facility to capture large rock blocks;
The tunnel has a total length of 100 m and a clear height of 5.00 m, ensuring the passage of vehicles with the largest gauge;
The columns of the facility "step" on piles with a diameter of 1000 mm and depths of 10.00 and 12.00 m, united by a pile-over beam. The tunnel slab is 0.6 m thick;
A drainage and water supply system has been implemented, elastic safety fences have been installed, new asphalt pavement, markings, signs and signaling have been installed.
