The Maslenica Bridge (Croatian: Most Maslenica, also known as Croatian: Maslenički most) is a deck arch bridge carrying the D8 state road approximately 1 km (0.62 mi) to the west of the settlement of Maslenica, Croatia and 500 m (1,600 ft) south of the D54 and D8 state roads junction. It was built in 2005 on a site of a similar bridge that was destroyed in 1991, during the Croatian War of Independence.
The bridge is 315.3-metre (1,034 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 (9.8 in) thick reinforced concrete deck slab is supported by the cross-girders set 2.19 m (7 ft 2 in) apart and the longitudinal girders set 8 m (26 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 2,300 mm (91 in) wide. The arch spans 155 m (509 ft), with an arch rise of 41.45 metres (136.0 ft). The arch comprises a box cross section and provides a 55 m (180 ft) clearance below the 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.
The bridge was destroyed by explosives on November 21, 1991 during the Croatian War of Independence. Prior to its demolition it represented the last road link between Zagreb and Split left intact within the territory controlled by the government of the Republic of Croatia thereby being of immense importance.
