Polish Corridor
The situation regarding the Free City and the Polish Corridor created a number of headaches for German and Polish Customs. The Germans requested the Free City of Danzig and the construction of an extra-territorial highway (to complete the Reichsautobahn Berlin-Königsberg) and railway through the Polish Corridor, connecting East Prussia to Danzig and Germany proper. Poland agreed on building a German highway and to allow German railway traffic, in return they would extend the non-aggression pact for 25 years.
