Progetti

The project concerns the upgrading to four-lane of the route Palermo-Agrigento (SS 121 – Catanese) in the stretch from the junction with the A19 PA-CT Motorway (location Ficarazzi) until the junction with SS189 beyond the village of Lercara Friddi (about 50 km). The new route involves a 23 m wide and 20 m long mountain road including:

• twenty-two viaducts for a total length of 15 km (about 27% of the total stretch)
• thirteen tunnels dual carriageway for a total length of 23 km (about 42% of the total stretch)
• ten big intersections

During  2003-2004 SERING has carried out the Preliminary design in association with ATKINS.

Services provided by Sering

• Environmental Impact Assessment
• Preliminary design

In 2007, the Client requested the review and updating of the preliminary design and the EIA following new project requirements. In this context, Sering developed a new Preliminary project for the solution chosen.

The Environmental  Impact  Assessment included

• Field surveys (traffic vibration, noise record)
• Study of environmental and territorial constraints;
• Noise and air pollution analysis before and after works and choice of necessary mitigation works
• Analysis and interpretation of traffic vibration on structures
• Design of restoration of green works
