In 2006, the construction of the Grau Expressway was completed, whose extension covers 3 km.[2] This expressway extends from Plaza Grau to Jirón Lucanas, and is intended for the exclusive transit of public transport units and feeder buses to the Metropolitano. The elevated viaduct of Line 1 of the Lima Metro crosses part of its central berm, in the section between Aviación Avenue and Locumba Street.[3]
