The next phase of redevelopment at Rome's Termini's station is set to begin early next year. The works will include the construction of two car parks, one over the rail-tracks and another on nearby Via Giolitti, and the creation of an underpass for cars that will link the beginning of Via Marsala to Via del Castro Pretorio and Via Giolitti. Piazza dei Cinquecento in front of the station will be transformed into a pedestrian precinct that will extend from the station entrance to the Baths of Diocletian. It is not yet clear what will happen to the bus terminus in the piazza but a new location is being studied by Grandi Stazioni (the company that runs Italy's principal railway stations), Rome's city council and the city's public transport company ATAC. The aim of the project is to relieve traffic congestion in the busy station area and to finish the refurbishment begun in 1998. The two sides of the station will be connected above the platforms by a pedestrian pathway lined with shops.
