The challenge in this Monumental city with stone buildings in a very compact placement, is to find the possibility to realize a Bypass toward the Centre by fulfilling these conditions. • Not ruin buildings because it is a Protected Zone and most of them are monuments of the 1st category and others of 2nd category. • The road must fit in the urban morphology of the city • Must respect the existing Landscape Must be integrated in the best way to the existing scheme in a natural and fluid circulation • Must save the continuing connection between the different quarters of the city and not create artificial conditions that large areas remain on difficult communication with the city Centre. • The Centre and each zone must have the opportunity to be visited normally by the residents also carrying their goods, tourists and the elder people, under optimal conditions.
