 Valparaíso's road infrastructure has been undergoing substantial improvement, particularly with the completion of the "Curauma — Placilla — La Pólvora" freeway bypass, which will allow trucks to go directly to the port facility over a modern highway and through tunnels, without driving through the historic and already congested downtown streets.In addition, roads to link Valparaíso to San Antonio, Chile's second-largest port, and the coastal towns in between (Laguna Verde, Quintay, Algarrobo, and Isla Negra, for example), are also under various degrees of completion.Travel between Valparaíso and Santiago currently takes about 80 minutes via a modern toll highway.
