The Road Bypass to SP65 "Futa" near the town of Rastignano is the main expansion of the road system in the South-east quadrant of the Bologna basin.

The new infrastructure goes through a highly anthropized territory; solving insertion issues was one of the main aspects of the project. The particular characteristics of the territory crossed made it necessary to adopt a large number Bridges, culverts, and retaining walls as well as a multitude of interventions complementary to the project and so the final value of the work amounted to 53 million euros.

In particular during the final design the following activities were carried out:

• Study of the roadway (approx 2800m) and of the four junctions with the existing road network;
• Design of major structures: 2 steel-concrete viaducts (5 spans of 45 or 58m for a total of 265m and 5 spans from 30m to 60m for a total of 220m) on the Savena stream; one cut & cover tunnel of about 125m and a thrust reinforced concrete box to solve two intersections with the Bologna-Florence railway line;
• Minor structures consisting of 8 culverts and many retaining walls with heights up to 8m;
• Design of hydraulic works for safety improvement of Savena stream for a portion of about 2 km (riverbed re-shaping, bridle, counter-bridle, fish ascent ramps);
• Rainwater disposal, phytodepuration and public lighting facilities;
• Green and environmental mitigation works (noise barriers, architectural elements of shielding the structures of one of the viaducts);
• Restoration and consolidation of a historic bridge;
• Impact and environmental mitigation study in particular with regard to some components: noise, air, soil, subsoil and landscape;
• Study of the construction site, of impacts during construction and related mitigations;
• Elaboration of virtual models with simulation of the construction works;

Enser has also been involved in the coordination of all geognostic investigations and survey activities and all the studies preparatory to the design (geology, geotechnics) as well as the contact with all the competent bodies.  A total of 63 reports were drawn up, including administrative papers, and some 400 project drawings were issued in various versions as the design phases progressed.
