Structure

The bridge is 315.3 metres (1,034.4 ft) long, measured between the abutments, comprising a steel arch supporting a reinforced concrete deck executed as a continuous girder across 17 spans: 17.52 m (57.5 ft) + 2 x 19.71 m (64.7 ft) + 19.68 m (64.6 ft) + 7 x 17.52 m (57.5 ft) + 19.68 m (64.6 ft) + 4 x 19.71 m (64.7 ft) + 17.52 m (57.5 ft). The deck structure comprises a grillage consisting of the deck slab with longitudinal girders and cross-girders. The 0.25 m (0.820209973753281 ft) thick reinforced concrete deck slab is supported by the cross-girders set 2.19 m (7.2 ft) apart and the longitudinal girders set 8 m (26.2 ft) apart and made composite. The bridge piers and spandrel columns comprise hollow square cross-section. Size of the squares (edge) varies depending on height of the piers and columns from 650 mm to 850 mm, except for the columns at the springing which are 2300 mm (90.6 in) wide. The arch spans 155 m (508.5 ft), with an arch rise of 41.45 metres (136 ft). The arch comprises a box cross section and provides a 55 m (180.4 ft) clearance below the bridge.

The first Maslenica Bridge

The original Maslenica Bridge was designed by Vojislav Draganić of Inženjerski Projektni Zavod (IPZ) between 1955 and 1960. By 1989, wear caused by heavy traffic and inadequate maintenance became significant, including cracks on the cross-girders and a pier. That led to a half-year long suspension of freight traffic across the bridge while it was repaired. The issues with the spandrel structure and the piers were remediated at that time by strengthening the pier and column cross-sections and by repairs to the cross-girder joints. During the summer of 1990, the bridge was once again in full operation, followed by another period of restricted use while the rehabilitation works were completed.

Unfortunately, the bridge was destroyed by explosives on November 21, 1991 during the Croatian War of Independence

The bridge was executed atop barges and served as the only road link between Zagreb and Split (that did not require use of ferries or occupied territories) between 1993 and 1995. The pontoon bridge was repeatedly attacked by artillery causing occasional damage or even sinking of individual barges which were subsequently replaced. After 1995 and conclusion of the Croatian War of Independence the pontoon bridge lost some of its importance as overland routes became available.

 started tender procedure regarding reconstruction of the Maslenica Bridge in its original form. The remains of the original bridge left over were pier foundations (some of them shifted or damaged) and the southern abutment. The reconstruction design was based on the original construction designs which were still available. All basic structural elements were left unchanged, while some changes were necessary due to changes to construction code implemented since completion of the original bridge. Most significant portion of those applied to earthquake safety. Overall width of the bridge increased from 9.4 m (30.8 ft) to 10.5 m (34.4 ft) and the piers and columns are reinforced. Furthermore roadway grade has changed somewhat and new types of safety railings are placed along the sidewalks. The reconstruction of the Maslenica Bridge was completed and the bridge opened on June 17, 2005.

The construction (or rather reconstruction) costs were 59.8 million Croatian kuna
