Within the scope of the Buca Onat Tunnel Project, which is planned to connect Buca Onat Street to the Intercity Bus Terminal and Peripheral Highway within the boundaries of Buca District, calculations for the tunnel body and exit portal were carried out for the left tube starting from Km: 1+127 and the right tube starting from Km: 1+150.

Detailed calculations for the tunnel were performed as part of the project, and three-dimensional models were prepared for the tunnel design.
