Autostrada A90 orGrande Raccordo Anulare (lit. 'Great ring junction') orGRA is a ring-shapedautostrada (Italian for "motorway") 68.2 kilometres (42.4 mi) long inItaly located in theregion ofLazio that encircles centralRome. It is a part of theE80 European route. GRA is one of the most important roads in Rome, and traffic reaches 160,000 vehicles per day as of 2011.
The GRA features 14 tunnels, with lengths varying from the 66 meters of Parco di Veio II tunnel to the 1,150 m (3,770 ft) meters of the Appia Antica tunnel as well as eight rest areas. It has 42 junctions, with theVia Aurelia numbered 1 and the rest following clockwise.
The motorway has always been toll-free. However, there are plans to introduce a fee for vehicles entering the GRA from highways. Maintenance costs are around€11 million per year.
Its acronym was given after one of its main designers and supporters, Eugenio Gra, chairman ofAnas, theItalian roads Authority, at the time of construction. The official number among the Italian motorways is Autostrada A90, but is widely known by Romans as Il Raccordo (lit. 'The Junction').
Plans for an orbital road around what, at the time, was considered to be the entire city of Rome were proposed by the end ofWorld War II. One of the designers' main purposes was to build the road as most equally distant as possible from the geographic centre of town, theCampidoglio, 11.4 kilometres (7.1 mi) away from the motorway.
Construction works started in 1948. The first section,Flaminia toTiburtina (north-to-east section) opened in 1952, later extended in stages. The last section to be opened was the west-to-north section (Aurelia to Flaminia), in 1970.
Although the GRA was initially planned and built as asingle-carriageway road, it was soon clear that traffic was rapidly growing well beyond the expectations. Construction works to motorway standards started in late 1950s with firstdual-carriageway, four-lane section (Salaria to Tuscolana) opened 1962. Further works were carried over throughout the 1970s, and by 1979, the remainder sections were widened to four-lane and the entire ring classified as toll-free highway.
Widening works to 6-lane started in 1983 and were completed in stages throughout the 1990s and 2000s. As of April 2008 97% of the GRA was 6-lane with final sections (new tunnel underVia Cassia) opened 2011.
Over the years the city of Rome has expanded well beyond the GRA, especially in the direction of neighborhoods such asOstia, Olgiata, Borghesiana andAlbano Laziale where Rome's built-up urban "tentacles" will reach up to about 15 kilometers in length from the ringroad outward.
It has been suggested that a second ring might be constructed in the future,[2] firstly as an attempt to alleviate congestion on the old one and secondly to offer access to a number of new industrial, commercial and residential zones built around it.Such a project would imply a new external ring-shaped orbital motorway of about 120 kilometres (75 mi), denominated NIA (Nuova infrastruttura anulare, "New ring infrastructure"), which would cost over €5 billion.
The road was the subject of the 2013 documentary filmSacro GRA which won theGolden Lion at the70th Venice International Film Festival.[3]
Although the nameGRA officially stands forGrande Raccordo Anulare ("Great Ring Junction"), the name was actually coined in order to make its acronym be the name of the head of the project, engineer Eugenio Gra.
