A1 Barberino - Incisa
A1Barberino - Incisa
Construction of lane 3 (59Km)
The intervention concerns the expansion of the stretch between Barberino di Mugello and Incisa from two to three lanes. This stretch, which is connected with the area in which the Variante di Valico works are being carried out, sees peak traffic of approximately 111,000 vehicles per day, with approximately 32,000 lorries and buses.
The Firenze Nord - Firenze Sud stretch is used by both long-distance traffic and local traffic that uses the A1 as an urban bypass.
Motorists will be guaranteed access to the same 2 lanes as before commencement of the works for the entire duration thereof.
The works are in three macro-stretch, as set out below.
BARBERINO - FIRENZE NORD STRETCH
A new 3-lane, southbound carriageway is scheduled for construction on this 17.5 km stretch.
Lastly, northbound traffic will use the 4 lanes on two carriageways of the suitably adapted existing highway.
FIRENZE NORD - FIRENZE SUD STRETCH
This 22-km stretch was expanded from 2 to 3 lanes, with some stretches in an alternative 3-lane tunnel route. On the alternative routes, the former south carriageway was redeveloped and opened to northbound traffic.
The Services Conference was concluded in October 1999 and an Environmental Observatory (Technical Warranty Committee) was set up in 2000 to ensure transposition of the prescriptions imposed by VIA and the Services Conference. Between March 2002 and July 2004, the Grantor approved those projects that had successfully passed Observatory verification checks. Work was allocated and commenced between October 2003 - October 2005.
Construction works were very complex, given that they concerned a region of great landscape value and a high population density.
The Firenze Nord - Firenze Scandicci stretch was fully opened to traffic in April 2007. The Firenze Scandicci – Firenze Impruneta and Firenze Impruneta – Firenze Sud stretches were fully opened to traffic in August 2013.
FIRENZE SUD - INCISA STRETCH
This 17.8-km stretch is expected to be expanded from 2 to 3 lanes.
The Municipalities of Calenzano, Sesto Fiorentino, Campi Bisenzio, Florence, Scandicci, Impruneta, Bagno a Ripoli and Lastra a Signa have entered into an agreement with Autostrade per l'Italia for a series of interventions between Firenze Nord and Firenze Sud, which mainly concern:
- new stretches of ordinary roads;
- 2 junctions on the SS 2 Cassia – SGC Firenze Siena;
- new road links with the city of Florence;
- environmental improvements and designing of high-value public areas over large areas;
- park and ride systems;
- public areas and green spaces;
- cycle paths.
A study was carried out by Euromobility on the stretch between Barberino and Firenze Nord, which predicts a marked reduction in air pollution on completion of the expansion works.
The expected results are as follows.
- CO (carbon monoxide) emissions: -18.0%
- NOx (nitrogen oxide) emissions: -22.0%
- VOC (volatile organic compound) emissions: -28.0%
- PM10 (fine dust) emissions: -24.0%
