Austrian police say that work on creating border controls at the main crossing to Italy is starting with construction scheduled to be completed by the end of May.

They say that crews will begin pouring concrete Tuesday for the foundations of a registration hall, barriers and other structures at the Brenner pass in response to an anticipated flow of migrants trying to enter Austria after arriving in Italy over the Mediterranean.

Austrian officials say migrants trying to reach prosperous EU countries will likely turn to that route, now that there is no free passage from Turkey into Greece and on through the West Balkans.

The Brenner crossing links the two countries with a multi-lane highway and a two-lane road, as well as rail tracks.
