It's toll-free over their entire length. Since 1999, the highway is officially designated as " A90 " refers to what has practically but not yet enforced because the signage still only has the abbreviation " GRA ".

" GRA "

The acronym " GRA " (large ring compound) is also a tribute to the engineer Eugenio Gra, the ANAS President at the time of planning the beltway. He was one of the main planners and supporters of the construction project.


First plans

Towards the end of the Second World War came on the proposal to build a ring road around Rome. One of the main goals of the planners was the road away as evenly as possible from the geographic center of the city to build the Capitol. They chose a distance of seven miles ( 11.4 km ). First, the road was built with the intention of the traffic that is not the center of Rome had as a goal, stay out of the city traffic. Only later she won in addition the importance of different roads on a possible short and efficient way to connect ( for example, the A1 with the former A2).

The construction

The work began in the late 1940s. The first section ( Flaminia Tiburtina ) was completed in 1952. By 1970, the road was partially expanded more and more, until finally with the Aurelia Flaminia section of the ring was closed.

Although the GRA was originally conceived as a two-lane road and was also built, the person responsible was quickly realized that the traffic density was much higher than initially assumed. Thus, the road was expanded to two lanes in each direction already in the late 50s. In 1979, in addition to the full length of hard shoulder were present, the Ringstrasse was finally classified to a highway.

In 1983 the work on a renewed widening to three lanes in each direction. Today, the entire GRA is six lanes ( three lanes in each direction).

Introduction of a toll

Due to the high volume of traffic and the high stress associated with the road surface has been discussed lately about the introduction of a toll, as it is already available on most Italian highways. Nevertheless, there are numerous factors that make an introduction quasi impossible:

  • The toll booths would exacerbate the already critical traffic situation.
  • For the tollbooths enough space needs to be created, especially at the respective exits that are very close together.
  • There is a strong resistance in the Roman population against such a proposal.


  • Among the inhabitants of Rome is only the designation Il Raccordo (English: The feeder ) familiar. The full name is only used in official documents.
  • In many maps not otherwise common name for the A90 will be used. Instead, one often finds the descriptions of " northern bypass ", " eastern bypass ", " southern bypass " and " Western Bypass ".
  • Despite the recent introduction, the numbered exits, it is rather common among the Roman citizens, after they name the exits intersecting streets. In addition, there are numerous inconsistencies in the numbering sequence, as always new connection points have been added, which no number has been assigned.
  • The Romans regarded the beltway often referred to as city limits, similar to the Parisian population périphérique their Boulevard. Everything that is outside of the ring is therefore not associated with the city of Rome.


  • In Fellini's Roma ( 1972) by Federico Fellini, a gigantic traffic jam on the GRA will be staged.
  • The Italian Gianfranco Rosi published 2013 Sacro GRA an award-winning documentary dedicated to people who live on and with the GRA.
