In an area of 4.7 acres, a playground called Metrópolix is being built.   It already has a monumental flagpole and a 727-200 airplane which will work as a flight simulator.   This flagpole has an altitude of 50 meters that raises a flag 25 meters wide and 14.40 meters long. Soon, a shrimp boat and a locomotive with a coach wagon and caboose will join this project.   A road safety park and a bicycle track will be built.   Several interactive programs will be given to kids and teenagers as well as road safety programs that will help them expand their knowledge about these means of transportation.
