Ruta (highway) 245 that runs along the east side of the Osa Peninsula just got a $30 million face lift. 8 bridges were constructed from scratch to make an all-weather road of the 21-mile stretch between Puerto Jimenez and Rincon south.
The improved highway is good for tourism. Now motorists can use it to reach roads that go to Parque Nacional Corcovado in dry or wet weather conditions.
Guayabo Ceremonial Center, Costa Rica was built between 300 B.C. and 1400 A.D.. It is considered the main pre-Columbian archaeological site in Costa Rica. It is believed to reflect a bridge between the Mayans and the Incas.
The Guayabo historic site is situated in the province of Cartago.
The location was nominated by the Costa Rican Engineer and Architects College for its fascinating and still functional aqueducts and cobblestone roads.
This is only the second pre-Columbian site in the Americas to receive such a designation. The first one is Machu Picchu in Peru.
