Rome, August 1 - Rome's mayor on Thursday declared his hope to turn a stretch of boulevard flanking the landmark Roman Forum into a completely pedestrian zone. The area already will be closed to private vehicles starting on Saturday morning at 5:30, but will remain open to buses, emergency vehicles and taxis with the exception of a 24-hour celebration from 19:00 Saturday evening to 19:00 Sunday evening. ''I am dreaming of arriving at the total pedestrianization of the Roman Forum during this administration,'' Mayor Ignazio Marino said. ''It is clear that offering Romans an alternative to (current) public transport would help total pedestrianization. Thus the completion of the metropolitan C line up to Piazza Venezia is one of the aspects that must be considered in a manner strictly connected to total pedestrianization,'' Marino added.
