History
Construction
The motorway was built in stages starting in 1956. It began with the Savona – Ceva stretch being inaugurated on 27 January 1960. Work began shortly after in 1961 on the Ceva – Fossano stretch, including a connection to the city of Fossano and to the SS 28 for Turin. In May 1970, the Moncalieri – La Rotta section opened, followed by the Marene – Fossano stretch in July of the same year. Finally, in 1972, the initial Turin – Moncalieri – La Rotta section was built, with a separate roadway to Carmagnola.The Fiat track
In 1972, a second roadway was put into operation in direction to Savona. This roadway was located in the stretch between Carmagnola and the Rio Coloré West service area. This roadway was used exclusively by FIAT as a test track for higher speeds. The track began three kilometers (approximately 1.86 miles) from the Carmagnola junction, with the terminal square being just before the service area. There is also a square that was used as a technical track at overpass number 33, just 25.400 km in. Claudio Maglioli was known to have used the track to try and bring a Lancia LC2 to the record speed of 387 km/hr in preparation for the Le Mans race.Dangers and safety concerns
The single roadway of the highway was considered very dangerous from marker 13 to 110 km, as the middle lane was used regularly for passing by both directions. Head-on collisions were common, with 91 incidents and three deaths in 1971 alone. For this, the highway was dubbed the "highway of death". At one point in 1980, the number of fatal accidents was so high, judicial authorities ordered the closure of the highway in the Ceva – Altare section towards Savona. This was ordered on 17 July 1980; not long after, on 1 October that year, the highway was reopened. The central passing lane was removed, and the speed limit was lowered to 70 km/h.Doubling
In 1973, the doubling of Savona – Altare began, with the inauguration being in 1976. Later on in 1989, plans to double the stretch from Priero to Altare began. Work began in December 1993 and ended in July 1995. Four exits ceased use: Moncalieri "La Rotta" at the 3 km marker, the Vicoforte sanctuary at 67 km, Montezemolo at 92 km, and Carcare. Sections of the plain were affected by works starting from Carmagnola using the sediment from the FIAT track. This began in 1991 and ended in 2001, which was also the end of the entire doubling plan.The highway today
Electronic speed control
In two sections of each roadway, the average speed is monitored by the Tutor system, implemented between the Carmagnola and Marene stations (both roadways), near Priero (north roadway only), and Quiliano (south roadway only). The effectiveness of the system in the Carmagnola – Marene section is considered limited due to the presence of the Rio Coloré Service Area in the section.Route table
Fossano Junction
The Fossano Junction, which is only a single roadway, have signs indicating the beginning and end of the highway. Signs indicate the overpass as being a part of the A6 highway. According to the internal numbering of Autostrade per l'Italia, the link is classified as a ''D06 branch.'' Legislative Decree 461 of 29 October 1999 included the link as national interest and classified it as part of the A6. The junction extends for 6.1 km from the start of the junction.References
