Increased investment in public transportation, however, has not changed the fact that San Juan is an automobile-reliant city and its fast growth has sparked urban sprawl. As of mid-2010, the government has approved plans for a redesign of this Puerto Rican city, featuring a new mass transit system, new roads and intersections, and more beach-access points. No cars will be allowed inside the oldest part of city (Old San Juan). The plans hope to remedy previous poor urban planning in the oldest section of the city, the Isleta, while curbing reliance on motor vehicles. The plans for redevelopment also hope to make the city more appealing in order to attract new residents, as San Juan has suffered from a shrinking population over the past 60 years.
