Other forms: overpasses
An overpass is a bridge carrying one road above another. Under the overpass, a concrete overpass, take the overpass.
It is the American word; British English says flyover for the same structure, and both keep underpass for the one that goes beneath. Overpasses are what let motorway traffic cross without stopping, which is the whole point of grade separation. Note that an overpass is measured for headroom, and bridge strikes by tall vehicles are a standing problem.
