Lima's road network is based mostly on large divided avenues rather than freeways. Lima operates a network of nine freeways – the Via Expresa Paseo de la Republica, Via Expresa Javier Prado, Via Expresa Grau, Panamericana Norte, Panamericana Sur, Carretera Central, Via Expresa Callao, Autopista Chillon Trapiche and the Autopista Ramiro Priale.
