Toulouse's new bridge spans the Calon River. Although it is called the New Bridge, it has a history of several hundred years. From the vicissitudes of the bridge, we can see that people in the past designed bridges and caves for flood discharge. Otherwise, when the winter snow melts, blood will flow into the river. Without flood discharge facilities, sea water will pour into the city. This design is very scientific. The new bridge is also a scenic spot on the Kalong River. You can pay attention to it when you visit.
