The Autostrada A3 is a motorway in Southern Italy, which runs from Naples to Salerno, in the region Campania. Until 2017 the route was much longer, going after Salerno further south until Reggio Calabria; on this year, this section became part of the new A2 motorway and of its two spur routes.
Overview
Due to sections not being originally constructed to anywhere near Motorway standard and to the notoriously poor conditions of maintenance, and also to the difficult terrain along some of the route, the motorway has been often taken as a symbol of the backwardness and economical problems of southern Italy. Italian historian Leandra D'Antone has defined it "a true Italian shame". The European Union declines to classify the road as a "motorway" due to the decades-long roadwork restrictions on a supposedly modern road and seeks recompense for its financial contributions.
On 22 December 2016 the Salerno-Reggio Calabria freeway was declared complete, 20 years after the first renovation works started, with the opening of Larìa tunnel in Cosenza. In a ceremony held in Reggio Calabria, prime minister Paolo Gentiloni begged pardon "for the delay" and the road name was changed from "A3 Salerno-to-Reggio Calabria" to "A2 Autostrada del Mediterraneo" (Highway of the Mediterranean).
History
The first stretch of the road to be completed was the Naples-Pompeii section, finished on 22 June 1929. The connection onward to Salerno was completed on 16 July 1961.
In 1964 the Italian government decided to build a motorway which connected the rest of Italy to Calabria, so far considered a kind of "Third Island" (together with Sicily and Sardinia), due to the nature of its terrain, which made it problematic to reach the region. The new motorway was built in a total of 8 years, the works being delivered on 13 June 1974.
The road built by 1974 is more similar to a sub-standard freeway (Italian: strada statale, "state road") than to the other autostrade (motorways) in Italy.
1997–2017 Renovation
Queues became a common feature, especially in summer. To solve the situation, the Italian government funded the construction of a new route which would remove the high gradients and sharp turns and enlarge the carriageway. This required the construction of new tunnels and viaducts (among these the viadotto italia the highest in Italy) while keeping the traffic on the current motorway open. The reconstruction works started in 1997 and officially ended in 2016 during a ceremony although works continued until late 2017. The EU antifraud investigation of works undertaken between 2007 and 2010 together with the repayment of over €300m to the EU in July 2012 have delayed completion of the upgrade works even further.
The cost of the upgrade (in August 2013) was projected to reach over €10bn by the time it was eventually completed, then envisaged as 2018. The section from Salerno to Reggio Calabria alone, 442 km long, would cost €10bn with the rest spent on widening/upgrades already completed between Naples and Salerno. €7.443 Bn had been spent up to 2011 on parts of the 442 km section between Salerno and Reggio Calabria.
Construction
The entire road was constructed as a substandard freeway by the mid-1970s and later an upgrade program from Naples to Reggio Calabria started in the early 1990s. The section with three lanes in each direction has a length of 105 km, between Naples and RA02 which goes towards Potenza. The section from the interchange with the A1 motorway in Naples to the Pompeii exit, built during the 1920s, originated as a local turnpike, and was later retrofitted to motorway standard. Many of the junctions along the original A3 route completed in the 1970s had very tight corners and extremely limited deceleration fields; this is especially significant on the now more than 50-year-old Naples-Salerno section, where at some junctions there are stop-signs for traffic entering the motorway. Hard shoulders only appeared along the route as part of the post 1990 upgrades, with only occasional emergency bays at infrequent locations on the sections that have not been upgraded yet.
The concession of the Northern part was owned by , a company listing in Borsa Italiana and a subsidiary of Autostrade per l'Italia, which in turn a subsidiary of Atlantia. The southern segment (Salerno-Reggio Calabria) is toll-free and is maintained by ANAS, the state agency for public routes. Located in a mountainous area, it is prone to very high levels of traffic (especially at the start and at the end of holiday periods).
