South Urban Round of Mairena del Aljarafe

The work consist of the duplication of the current A-3120 road, particularly the section between Palomares del Río  and Urbanization Ciudad Almar. In addition, connections will be made between the Elliptical roundabout of Ciudad Expo and the variant itself by executing two road junctions of 577m and 495m respectively.

Duplicating the existing axis, means the execution of a total of 9 roundabouts that collect and distribute all the traffic of the southern area of Mairena del Aljarafe.
