The Fulda Gap Modification for Wargame: Air Land Battle is designed to provide campaigns for the three major combatants in a hypothetical conflict between WARSAW and NATO forces. Forces for the campaign have certain preset variables but can be changed by the player as per his liking many elements of the unit availability and timeline range have been modified to fit into a reasonable expectation of probability for each country’s military capability.
In the Cold War Soviet war planners from the Eight Guards Army Staff near Weimar all the way to the Ministry of Defense in Moscow probably had a codename for this avenue in the westbound mode. Maybe it was "Rhinegate". (We will update this line when we learn exactly what they called it.) Anyway, you do not have to be a war planner to look at the map of Germany and recognize that the shortest** route from East Germany to the Rhine River was THIS avenue.
** See map (The alternate avenue, the North German Plain - region between the Berlin-Cologne autobahn and the North Sea coast, is traversed by two major rivers and a maze of shipping canals with steep banks. Its is about twice as long as the Fulda Gap and its reaches the Rhine where it is about twice as wide as in the Frankfurt - Wiesbaden sector.)
