A1Casalecchio - Sasso Marconi
construction of lane 3 (4 Km)
The intervention saw expansion of the A1, between 195 km and 195 km, from two to three lanes plus the hard shoulder.
Casalecchio - Sasso Marconi is the stretch upstream of the Variante di Valico and is the starting point of the broader expansion plan of the A1 stretch between Bologna and Firenze that sees average daily traffic volumes that are far in excess of those recorded in the entire Autostrade per l'Italia network.
The plan required preliminary definition of the design of the Casalecchio rail and road junction, which was completed in June 2003 with the support of ANAS, RFI, Autostrade per l'Italia and the Municipality of Casalecchio.
The Conference of Services came to an end in May 2005.
The work was contracted out on 21 March 2006 with opening to traffic in 2009.
Motorists were able to use the same 2 lanes as available prior to commencement of the works, throughout the intervention.
Two artificial noise abatement tunnels have been constructed (at Calzavecchio hill and in the Ceretolo area) and 3.8 km of noise barriers installed.
