The main north-south thoroughfare, the Cardo Maximus, was originally a paved avenue approximately 22.5 meters wide (roughly the width of a six lane highway) which ran southward from the site of the Damascus gate, terminating at an unknown point. The southern addition to the Cardo, constructed under Justinian in the 6th century AD, extended the road further south to connect the Church of the Holy Sepulchre with the newly built Zion Gate. Along its length, the roadway was divided into three parts: two colonnaded covered walks flanking a 12 meter wide road. The shaded porticoes provided separation of pedestrian traffic from wheeled carts, shelter from the elements, space for small-scale commerce, as well as opportunities for residents and visitors to gather and interact. The central open pavement provided commercial access as well as ritual space. The Cardo's most striking visual feature was its colonnade, clearly depicted on the Madaba Map.
