Autovie Venete S.p.A is the managing Company of motorway routes A4 Venice-Trieste, A23 Palmanova-Udine South, and A28 Portogruaro-Pordenone-Conegliano. The Company started operating after the Second World War and its first achievement was the construction of a dual carriageway through the Karst area.

The Company, founded in 1928, became publicly-owned in 1950 and was, nine years later, assigned the construction and consequent management of the motorway routes Venice-Palmanova-Trieste, and Palmanova-Udine (total length 147 Km), part of which, the route Trieste-Udine, was officially opened in July 1966.

The establishment of the regional Autonomy of Friuli Venezia Giulia, in 1963, implied the restyling of Autovie Venete's administrative structure, in which the public administration maintained a major role.
Autovie Venete is not only active in the construction of facilities in North-Eastern Italy, but operates also in Central and Western Europe, by collaborating effectively with local authorities.
Indeed, its geographic position, in North Eastern Italy, offers a highly favourable environment to connections with Eastern Countries, particularly Slovenia, thanks to International crossings Fernetti in Trieste and Sant'Andrea in Gorizia.
As a consequence of the substantial increase in commercial relations between Western and Eastern Europe, the Company acquired importance as strategic reality, especially in Friuli Venezia Giulia, with its facilities playing a fundamental role in the framework of Corridor n. 5, the multi-modal axle, which will connect Barcelona to Kiev passing through Trieste, Ljubljana, and Budapest.
