Along the southern foot of the Calmont, running from west to east between the Moselle villages of Bremm and Ediger-Eller is the B 49 federal highway. East to southeast of the ridge is the 4,205-metre-long Kaiser Wilhelm Tunnel which runs from north-northeast to south-southwest and carries the Moselle railway from Cochem to the station of Ediger-Eller and then over a 281-metre-long bridge over the Moselle.
