The Upper Bridge originates from the 16th century and is inscribed in the Croatian Registry of Cultural Objects as part of the cultural-historical city of Nin. The bridge was built on low bearing capacity and soft soil. For the most part, the bridge deck is supported on the stone embankment while the passage of sea under the bridge is allowed through three vaults. During its 450 years of existence, the Upper Bridge has been destroyed several times due to river floods or damaged as a result of the ground settlement. In the catastrophic flood that occurred in 2017 the middle third of the bridge was completely destroyed. The presented project of bridge reconstruction and restoration solved the problem of foundation of the bridge and flow problem through the extended flow profile underneath the vaults taking into account the earthquake resistance, durability of the structure and original appearance of the bridge.
