The bridge comprises a span reinforced concrete arch, with an arch rise of . The arch comprises a box cross section, a double cell of constant depth. The superstructure is continuous across 12 spans, consisting of prestressed girders made monolithic with the in situ cast deck slab and transverse girders.
The bridge is maintained and operated by Croatian Motorways Ltd.
Approximately to the south, there is another bridge, carrying D8 state road across the same strait, and this was the original crossing point over the strait. Although that is a completely different structure, carrying a different road, that bridge is also officially called Maslenica Bridge. The bridge carrying the A1 motorway is actually older than the one carrying the D8 road, however since the latter is a replacement for a bridge destroyed in the Croatian War of Independence
The Croatian War of Independence was fought from 1991 to 1995 between Croat forces loyal to the Government of Croatia—which had declared independence from the Socialist Federal Republic of Yugoslavia (SFRY)—and the Serb-controlled Yugosl ...
in 1991, both A1 and D8 bridges are known to be referred to as both ''old'' and ''new'' ''Maslenica Bridge''.

, between 1993 and 1996, using free cantilevering with temporary cable-stays. The reinforced-concrete arch was executed in long segments, matching spandrel column spacing. Prefabricated girders required for the structure were executed and prestressed in a purpose built plant on the site. The same plant was subsequently used to produce Jersey barrier

The bridge is significant as it is the first motorway reinforced-concrete arch bridge comprising a substantial span executed in Croatia.

Subsequently wind protection structures have been executed along the motorway section comprising the Maslenica Bridge, since the long section was completely closed to traffic due to strong wind from time to time - for a total of 6 days and 19 hours in 2007, and 13 days and 2 hours in 2006.
