Cut & cover Dobrava

The purpose of the Dobrava cut and cover structure is the crossing of wild animals as well as principal road over the motorway. The arch-shaped cut and cover structure with a single span of 39 m was constructed due to favourable geological conditions and sufficient depth of the cuts. Portals are inclined so the total width of the structure is 44 m at the apex of arch and 67 m at the foundations. The structure consists of four longitudinal segments. The height of embankment ranges between 3.0 to 4.0 m above the apex of the arch.

The solution is aesthetic and economical, and enables animal-friendly passing over the motorway and creates a pleasant impression on the users.
