Bridges are engineering wonders. These bridges are wonderful and amazing structures that are made to connect places that otherwise might have been left isolated. Each and every one of these long bridges is incredible in its own way. We have compiled a list of the longest bridges in the world with pictures and descriptions. Those beautiful photos are showing to us that there are no borders and everything is reachable. Let’s take a look at those longest bridges in the world:
