Route

The Eurasia Tunnel connects Kennedy Street on the European side with the D-100 Highway on the Asian side. By using the Tunnel, one can easily reach the Fatih district, historical peninsula and Atatürk Airport on the European side, and Kadıköy, Üsküdar and Göztepe districts via the D-100 Highway on the Asian side.

In 2003, a pre-feasibility study was conducted for the Bosphorus crossing based on the findings of the Transportation Master Plan Survey prepared by Istanbul University in the name of the Istanbul Metropolitan Municipality in 1997. Accordingly, it was determined that a road tunnel be constructed under the Bosphorus based on the conclusion that a new bridge on the Bosphorus would lead to significant environmental problems as well as additional planning and design challenges. In 2005, a feasibility study was conducted to examine existing route options for the Tunnel. Based on this feasibility study, the present route was adopted, due in large part to the following reasons

  • Equal distribution provided by the location of the Tunnel in connection with the existing two bridges on the Bosphorus;   
  • The lowest investment cost due to the shortness of the Tunnel;
  • Availability of sufficient area for the establishment of the construction sites and operational facilities (toll plazas, operations buildings).

Eurasia Tunnel can be accessed from Kazlıçeşme, Kocamustafapaşa, Yenikapı and Kumkapı on the European side and Acıbadem, Uzunçayır and Göztepe on the Asian side.

Entry and exit points for the Tunnel are located in Koşuyolu on the Asian side and Kumkapı on the European side.

Toll Fee

The Republic of Turkey Transportation Ministry announced the one-way toll for 2018 to be TL 23,30 for cars and TL 34,90 for minibuses. Tolls are charged in both directions.

Pass violation fines can be paid via banks, Eurasia Tunnel’s website or mobile site and here. Payments can also be made via credit card.

You can check your pass status on the Eurasia Tunnel website or mobile site and also by clicking here .

The toll will be paid without the need to stop by using the Express Toll Collection System (HGS) and Automatic Toll Collection System (OGS) with the help of the state-of-the-art technology free flow portal. There are no cash payment plazas in the Tunnel.

You can check your account status easily via our website www.avrasyatuneli.com and safely pay any outstanding fees, if any, using your credit/debit card. Outstanding fees can be paid without a late fee if paid within 15 calendar days; after 15 days, the outstanding amount plus incurred fines are due.

If you don’t have a sufficient balance in your HGS/OGS account at the time of your passage from the Eurasia Tunnel, your account will be checked for the next 15 calendar days and your toll fee is collected automatically if and when sufficient funds are deposited in your account. If you fail to pay the fee in 15 calendar days, a fine of 4 times the original fee will be charged.

Please refer below to Paragraph 5, Article 30, Section 5 of Law No. 6001 on the Organization and Duties of the General Directorate of Highways regarding the imposition of fines.

“The owners of vehicles that use the highways whose operating rights were transferred or granted or the highways with access control under Laws No 4046, 3465 and 3996 without paying their toll are imposed by the operating company a fine at the sum of four times the toll they are normally to pay for the part of the road they used in accordance with the general provisions. Sixty percent of the total sum of the fine collected is paid by the operating company as a share of the Treasury to the Tax Office it is registered with in terms of the annual corporate tax payments via a declaration whose method and content is determined by the Finance Ministry. Where the operating company fails to declare such Treasury share or declares it less than the proper sum, or fails to pay such sum on time after declaring it, relevant tax office monitors and collects such sums together with the default interest that becomes payable under Article 51 of the Law No. 6183 for the period between the due date and the actual collection date in accordance with the pertinent provisions of the Law No. 6183.”

Yes, vehicles will be able to travel through the Tunnel by making payments via HGS and OGS systems. There are no cash payment plazas.

  • Toll payments for the Eurasia Tunnel pass can be made via the free flow portal by using HGS and OGS.
  • Since there are no cash payment plazas at the Eurasia Tunnel, drivers are required to obtain their HGS or OGS cards from PTT branches, sale points at the entry/exit of state highways or from contracted banks.
  • Please make sure that you have a sufficient balance on your HGS or OGS account to cover your toll at all times. (Car: TL 23,30 / Minibus: TL 34,90)
  • Any pass from the Eurasia Tunnel without the required balance on your HGS and OGS cards will be deemed a “Pass Violation” just as on toll highways and bridges.
  • In the case of a pass violation, you can easily query your status on our website www.avrasyatuneli.com.
  • You can safely pay any outstanding amounts via credit card without a fine within 15 calendar days.
  • However, the law stipulates that if the balance of your account fails to cover fees or you do not pay the outstanding amount within 15 calendar days, a fine in the amount of 10 times more of the original toll will be imposed on your pass violation.

Safety

Traffic is managed via the Smart Transportation System mounted inside the Tunnel and on the approach roads, the SCADA System, which ensures the control of the equipment inside the Tunnel, expert operators and patrol teams. Traffic is managed using instruments at the Toll Plaza barriers to ensure a smooth flow of traffic by assessing information received about average speed and load sensors.

Specialized police patrol teams are sent to incidents, which are instantly monitored by operators in the Tunnel Control Room and the SCADA system, ensuring that the accident is responded to in the shortest possible time.

First response vehicles that have been specially designed for the Eurasia Tunnel have been duly equipped to make the first intervention in any accident

It is possible to respond to fires using fire trucks that are specially designed for the Eurasia Tunnel. In addition, fire extinguisher cabinets are situated every 65 meters inside the Tunnel and can be used to combat fires. The Istanbul Fire Department can reach the site of an incident in the shortest amount of time possible as per the protocol signed with them.

In case of a fire, Tunnel users shall leave their vehicles and move to the next deck using the nearest escape stairs. Jet fans at the other side from where the fire broke out will run in the opposite direction to circulate fresh air from outside and prevent recirculation of smoke between the two levels. The fans at the level where the fire broke out will be run full circle and the smoke will be pushed out of the ventilation shafts and not recirculated inside the Tunnel.

The impact to be generated by an earthquake with Mw 7.25 magnitude on the Eurasia Tunnel, which is an average of 17 km distance from the Main Marmara Fault, will be an average magnitude of Mw 8 according to EMS’98 and MMI scale. However, the earthquake design of the Eurasia Tunnel will ensure that the Tunnel will suffer no damage in the event of an earthquake with a magnitude of Mw 9.

Due to the fact that there was a release of stress on the tectonic plates caused by the 1999 Kocaeli earthquake, and there has been no earthquake stronger than Mw 7 magnitude on the Main Marmara Fault Line since 1894, the possibility of an earthquake with a magnitude of over Mw 7.25 has been calculated to be 2 or 3 percent per annum. Therefore, the Eurasia Tunnel has been constructed so it will suffer no damage, even in an earthquake of 9 Mw magnitude.

Tow trucks that are specially-manufactured according to the structure of the Tunnel are used to evacuate disabled vehicles from the Tunnel.

Emergency Response Plan and Operational Security Protocol were prepared in cooperation with the Emergency Services (Police, Istanbul Metropolitan Municipality, Ambulance Services, Fire Department, Disasters and Emergency Management Directorate). More information on this can be found on the Operational Security video on the website and in security brochures.

Maximum allowed speed in the tunnel is 70 kilometers per hour. Drivers are reminded of the speed limit in the Tunnel by the vehicle monitoring system, radio announcement system and traffic signs. The speed inside the Tunnel will be managed by the Tunnel Speed Limit Control System (TEDES), established in coordination with Istanbul Metropolitan Municipality and Security General Directorate, as in other existing tunnels in Turkey. Security General Directorate fines drivers exceeding the 70 km/h speed limit inside the Tunnel and on the approach roads.

Operators in the Operation Control Center monitor all systems on a 24/7 basis. Emergency teams stationed at the portal areas and patrolling the Tunnel will respond immediately to any situation. Emergency services are always ready to enter the Tunnel.

  • Automatic Accident – Incident Investigation and Closed Circuit TV (CCTV) System

The maximum speed limit inside the tunnel is 70 km/hour.

The speed inside the Tunnel will be controlled by the Tunnel Speed Limit Control System (TEDES), established in coordination with Istanbul Metropolitan Municipality and Security General Directorate, as in other existing tunnels in Turkey.

Structural Characteristics

The Eurasia Tunnel has been designed for use by light vehicles (car, minibus). Vehicles higher than 2.80 meters, two-wheeled vehicles (motorcycle, bicycle) and pedestrians are never allowed to use the Tunnel.

Two-way GSM and internet communication is possible inside the Tunnel.

The Marmaray was designed solely for use by rail system while the Eurasia Tunnel Project was designed solely for use by light vehicles (cars, minibuses). The Marmaray was constructed by laying down tube tunnels at the bottom of the Bosporus. A two-level road tunnel was constructed under the seabed of the Bosphorus in Eurasia Tunnel Project.

The Eurasia Tunnel was designed to withstand the biggest possible earthquake that may take place on the North Anatolian Fault Line (which is estimated to be 7,2Mw ), and two additional special seismic joints were put in place in order to further strengthen the Tunnel. Additionally, 2 meter high walls were constructed on the European side to protect the Tunnel from a possible tsunami.

Environment

In many ways, the Eurasia Tunnel has benefits for the environment. It contributes to the reduction of fuel consumption and harmful gas emissions in the air by shortening driving distances. Reduced traffic jams, thanks to the Eurasia Tunnel, also helps reduce pollution by reducing congestion and long waiting periods in traffic. A comprehensive Environmental and Social Impact Assessment (ESIA) report was prepared for the Eurasia Tunnel, and a highly sensitive approach was adopted concerning impacts on the environment. International finance organizations that sponsored the project monitor the ESIA process meticulously, with controls conducted on the implementation of the ESIA management during both construction and operation phases.

You can access the ESIA documents here.

The Eurasia Tunnel Project was developed as a synthesis of the most important tunnel projects in the world and the knowhow obtained in this sphere. All potential environmental and social impacts of the project have been defined under the comprehensive ESIA study conducted under the project. Impact-reducing measures were identified in order to minimize, eliminate or create positive impacts.

You can access the Environmental and Social Management Plan (ESMP) by clicking here. Additionally, the UNESCO World Heritage Center is periodically updated about the current state of the project, and its comments are taken into consideration.

Reports were prepared for air quality both inside and outside the Tunnel in accordance with international standards. Upon the assessment of these reports, all of the parties that have both prepared and supervised the project concluded that the mechanical ventilation system with 2 extraction vents was appropriate and sufficient for the Eurasia Tunnel.

Exhaust emissions will be conducted to the shafts by a total of 92 jet fans – 46 jet fans on each level – and will be absorbed by 4 axial fans, one of which is spare. The ventilation shaft on the Asian side was designed 25 meters above the ground – 28 meters in total – to avoid any impact on high buildings nearby such as Siyami Ersek Hospital. The shaft on the European side was designed 5 meters above the ground – 20 meters in total – to avoid any impact on the silhouette of the city in accordance with the decisions of Istanbul Board No 4 for Cultural and Natural Heritage Preservation, and all the ventilation system was prepared accordingly. Two air quality monitoring stations were established by the Designated Company (Avrasya Tüneli İşletme İnşaat ve Yatırım A.Ş.) near the ventilation shafts on each side In order to monitor outside air quality. The data obtained from these stations will be shared with the public through the National Air Quality Monitoring Network.

In coordination with the Ministry of Transportation, Maritime and Communication, the Designated Company has dedicated an area for building an air treatment plant in each of the two ventilation buildings inside the Tunnel against the possibility of breaching air quality standards due to unexpected climate change, and will implement this step as needed.

Additional information and technical reports may be obtained from the Ministry of Transportation, Maritime and Communication.
