Interchanges are great! Why? Because unlike standard intersections, they allow free flow of intersecting roads rather than having to stop at traffic lights or roundabouts. But sometimes interchanges can be extremely complicated with many junctions and even several levels (those are called stack interchanges). Such a complicated interchange is sometimes nicknamed “Spaghetti Junction“. Take a look at these photos of mind-blowing interchanges and it will become very clear why

1. Puxi Viaduct, Shangahi, China – Perhaps the only stack interchange in the world with six levels, this huge interchange of Nanbei Road and Yan’an Road is located in Puxi – historic center of Shanghai
