4Octavio Frias De Oliveira Bridge, Brazil
What the 2008 built bridge lacks in historical heritage, it makes up with architectural ingenuity. The bridge was built by 450 workers over a period of 5 years. What makes the bridge unique is its x-shape in the center. Also, it has not one but two levels of vehicle crossing. It sparkles with innumerable LED lights that make it look nothing short of surreal. During Christmas and other festivals, Octavio is lit up to resemble a Christmas tree.
Very inspiring
