Via Stabiana is a primary road running north-south through Pompeii. Also named Cardo Maximus, it demonstrates features of the city’s main streets, none of which are wider than ten feet. They were constructed with large, uneven rocks with significant gaps between them. The polished surface is the result of centuries of traffic, evidenced by the deep grooves caused by passing chariots and carts. Sidewalks sometimes flanked both sides yet the traffic flow was often one-way. The two large boulders are stepping stones to keep your feet dry when water flows between the tall curbs.
