Map of the Brotherhood and Unity Highway

The Brotherhood and Unity Highway (Croatian: Autocesta "Bratstvo i jedinstvo"; Macedonian: Автопат „Братство и единство“; Slovene: Cesta bratstva in enotnosti or Avtocesta bratstva in enotnosti, Serbian: Autoput "Bratstvo i jedinstvo", Аутопут "Братство и јединство" was a highway that stretched over 1,182 km (734 mi)[1] across former Yugoslavia, from the Austrian border at Rateče near Kranjska Gora in the northwest via Ljubljana, Zagreb, Belgrade and Skopje to Gevgelija on the Greek border in the southeast. It was the main modern highway in the country, connecting four constituent republics.

Construction began on the initiative of President Josip Broz Tito, who called the project the "Road of brotherhood and unity" (Autoput bratstva i jedinstva) after the motto of the League of Communists of Yugoslavia. The first section between Zagreb and Belgrade was built with the effort of the Yugoslav People's Army and volunteer Youth Work Actions and was opened in 1950. The section between Ljubljana and Zagreb was built by 54,000 volunteers in less than eight months in 1958.[2]

Its importance caused it to be colloquially named autoput or autocesta (generic Serbo-Croatian expressions for "highway", "motorway"). This use has since largely faded out, after the successor states built further motorways.

In the 1960s and 1970s the autoput became a much frequented holiday route for Turkish immigrants in West Germany and Austria (then called Gastarbeiter) visiting their original homeland during the summer vacation time, and for tourists to southeastern Europe. Entering communist but non-aligned Yugoslavia was far easier, for people from NATO countries such as West Germany and Turkey, than entering any of the Warsaw Pact communist countries of the Balkan region that might have provided alternative routes.

Originally an ordinary road, the carriageway used to be congested with cars and trucks, especially in summertime, when overtired long-distance drivers caused numerous accidents. Wrecked cars usually remained in place for long periods of time, providing a grim reminder of the dangers of the highway. The situation slightly improved after some parts were brought up to modern motorway standards (two lanes for each direction plus an emergency lane) on the following sections built between 1977 and 1991:

In 1991, several sections were affected by the Yugoslav wars, bringing severe damage, and causing the traffic to be almost completely discontinued in places.

International categorization[edit]

Since 1975, the road was concurrent with the following routes of the International E-road network:


Since 1994 the route is also part of the Pan-European corridor X that extends from Salzburg to Thessaloniki.

The road has been continuously upgraded. As of 2011, it is a modern motorway in its entire length through:

and most of its length through:

As of 2018, the only remaining non-motorway sections are a total of 34 km (21 mi) in southern Serbia around Grdelica Gorge.
