First, don't hang up. Because the overpass is used for diversion, telling you how to get there, knowing the name of the bridge is of little significance to drivers and pedestrians.

Second, there is a name, because after all, it has to be managed. Many names are customary, so they are called Shunkou, or there are sponsors downstairs. It may also be displayed on GPS, and the locals know it more or less.

An overpass is an overpass or intersection, and an overpass is a viaduct, which can be a part of an overpass. These two concepts are different.
