After the signing of the Schengen Agreement in 1992 and Austria's subsequent entry into the European Union in 1995, customs and immigration posts at the Brenner Pass were removed in 1997. However, Austria reinstituted border checks in 2015 as a response to the European migrant crisis. In April 2016, Austria announced it would build a 370-meter long fence at the Pass but clarify that it would be used only to channel people and was not a barrier.
