'''Build the Gotthard Tunnel''' is a [[decision]] available to {{Flag|Switzerland}}. It builds the 15 kilometer long [https://en.wikipedia.org/wiki/Gotthard_Tunnel Gotthard Tunnel].

It requires that Switzerland has invented [[Machine Tools]] and owns the province of Lucerne (ID 606). Switzerland owns the province in the beginning of the game. It gives {{Green|4}} levels of [[railroad]] in Lucerne as well as {{Green|10}} prestige. Illogically the decision doesn't actually require you to have researched [[Industrial_technology#Infrastructure|any level of railroads]], and the decision can actually give a higher level of railroad, than would be possible to build with the current technology.
