The road platform is typing D “sliding city” at one lane per direction of travel of 9.5 m width. The intervention includes the constructions of 3 roundabout intersections, an artificial tunnel with a railway underpass, a highway underpass, the extension of a highway underpass, and two other road underpasses.
