The Gran Sasso Tunnel is part of the A24 Motorway that links Rome and the Adriatic Sea via L'Aquila and Teramo, through the Apennine Mountains via the Gran Sasso in Abruzzo. [1]

There are two tunnels, each with two lanes for each direction, 10,176 metres long. Construction started on November 14, 1968. The eastbound tunnel (to Teramo) opened on December 1, 1984 while the westbound tunnel (to L'Aquila) opened in 1995. Costs for the entire project amounted to approximately 1,700 billion Italian liras (nearly €890 million) - instead of the initially foreseen 80 billion Italian liras, due to unforeseen circumstances. [2]

The tunnels host the Laboratori Nazionali del Gran Sasso, the largest underground research center in the world. This underground laboratories are used by the INFN (Istituto Nazionale di Fisica Nucleare - National Nuclear Physics Laboratory) for experiments that require a low background environment in the fields of astroparticle physics and nuclear astrophysics. Construction works started in 1982 and ended in 1987. These labs are located approximately 1,400 metres under the Gran Sasso massif, protecting the experiments from cosmic rays. [3] [2] [4] [5]

It is the third longest road tunnel in Italy, after the Fréjus and Monte Bianco tunnels, and the longest road tunnel entirely on Italian territory. It's also Europe’s longest double-barrel tunnel, ranking twelfth in the world. [2]

The highway over the mountain, which now sees little traffic, has been renamed the Grand Highway of the Gran Sasso and Monti della Laga National Park to highlight its status as a scenic route.

Abruzzo, historically known as Abruzzi, is a region of Southern Italy with an area of 10,763 square km and a population of 1.3 million. It is divided into four provinces: L'Aquila, Teramo, Pescara, and Chieti. Its western border lies 80 km (50 mi) east of Rome. Abruzzo borders the region of Marche to the north, Lazio to the west and north-west, Molise to the south and the Adriatic Sea to the east.

The Istituto Nazionale di Fisica Nucleare is the coordinating institution for nuclear, particle, theoretical and astroparticle physics in Italy.

Astroparticle physics, also called particle astrophysics, is a branch of particle physics that studies elementary particles of astrophysical origin and their relation to astrophysics and cosmology. It is a relatively new field of research emerging at the intersection of particle physics, astronomy, astrophysics, detector physics, relativity, solid state physics, and cosmology. Partly motivated by the discovery of neutrino oscillation, the field has undergone rapid development, both theoretically and experimentally, since the early 2000s.

The DarkSide collaboration is an international affiliation of universities and labs seeking to directly detect dark matter in the form of weakly interacting massive particles (WIMPs). The collaboration is planning, building and operating a series of liquid argon time projection chambers (TPCs) that are employed at the Gran Sasso National Laboratory in Assergi, Italy. The detectors are filled with liquid argon from underground sources in order to exclude the radioactive isotope 39
Ar
, which makes up one in every 1015 (quadrillion) atoms in atmospheric argon. The Darkside-10 (DS-10) prototype was tested in 2012, and the Darkside-50 (DS-50) experiment has been operating since 2013. Darkside-20k (DS-20k) with 20 tonnes of liquid argon is being planned as of 2019.

The CERN Neutrinos to Gran Sasso (CNGS) project was a physics project of the European Organization for Nuclear Research (CERN). The aim of the project was to analyse the hypothesis of neutrino oscillation by directing a beam of neutrinos from CERN's facilities to the detector of the OPERA experiment at the Gran Sasso National Laboratory (LNGS), located in the Gran Sasso mountain in Italy. The CNGS facility was housed in a tunnel which diverged from one of the SPS–LHC transfer tunnels, at the Franco–Swiss border near Geneva. It used the Super Proton Synchrotron (SPS) accelerator as a source of high-energy protons.
