Human bones were found in the works of Dilovası's Bay Crossing Bridge. Ancient tombs were found in the works of the İzmit Bay Crossing Bridge in Dilovası, which has hosted many civilizations throughout history and has been an important transit point. Many bones were excavated from the graves found during the excavations. The bones, which are thought to be ancient tombs, were carefully packed in bags and delivered to the necessary institutions.
Although the graves were old, it is estimated that they belonged to ordinary people, not to important people in history. The fact that many graves are side by side raises the possibility of a possible cemetery in this region in the past. If there are other graves during the excavation works, bridge construction may be decelerated.
