Badal Tunnel

One of Türkiye’s important transportation projects, the Badal Tunnel, has been implemented on the Osmancık-Merzifon Road in Amasya. This tunnel, which connects the central Black Sea coast to inland areas in a north-south direction, is part of a transit corridor extending from the Iranian border to Bulgaria in the east-west direction. Developed by the Ministry of Transport and Infrastructure, the project aims to enhance traffic safety, improve accessibility, and deliver environmental benefits.

Project Overview

• Location: Amasya, Osmancık-Merzifon Road
• Tunnel Length: 921 metres (twin tubes)
• Connecting Roads: Total 3.6 kilometres
• Total Project Length: 4.5 kilometres
• Bridges: 4 bridges, total length 345 metres
• Cost: Approximately 120 million TL
• Opening Date: 19 January 2023
• Purpose: To improve road safety, bypass sharp curves, and prevent disruptions in winter travel.

Project Objectives and Contributions

1. Safer Transportation and Reduction of Traffic Accidents

The Badallar location where the Badal Tunnel was constructed was previously a high-risk area for frequent traffic accidents. This route, characterized by sharp curves, became especially hazardous during winter months due to ice formation and snow precipitation. With the completion of the tunnel, the together road safety standard has been elevated, significantly improving driver safety.

2. Environmental and Economic Benefits

• Time Savings: Travel time has been reduced compared to the previous route, providing a safer and more efficient transportation option.
• Fuel Savings: The elimination of sharp curves and steep gradients has led to reduced fuel consumption, resulting in economic benefits.
• Reduction in Carbon Emissions: The adoption of a more efficient road structure has reduced annual carbon emissions by 488 tonnes.

3. Role in International Transport

The Badal Tunnel is situated at a critical point along the transit hat corridor stretching from the Iranian border to Bulgaria. As such, it has established a vital transportation corridor for international logistics and trade. By making Türkiye’s east-west trade routes more efficient, the tunnel also contributes to the economic development of the region.

Technical Features and Construction Process

• The tunnel is designed as a twin-tube structure, with each tube measuring 844 metres in length.
• Together with connecting roads, the total project length reaches 4.5 kilometres.
• Four bridges were constructed as part of the project, with a combined length of 345 metres.
• Modern excavation and tunneling techniques were employed during construction, and specialized protection systems were developed to prevent rockfalls from mountain slopes.

Opening of the Badal Tunnel

The Badal Tunnel was officially opened on 19 January 2023 via a live connection by President Recep Tayyip Erdoğan. The opening ceremony was attended by Minister of Transport and Infrastructure Adil Karaismailoğlu, the Governor of Amasya, and other officials.

Bakan Karaismailoğlu stated during the opening speech: “The Badal Tunnel, one of the most important transportation projects in the region, will serve as a safety corridor for drivers and become a key component of Türkiye’s north-south and east-west logistics network.”
