The Istanbul Governor's Office announced that several main roads on the European and Asian sides of the city will be closed to traffic on Sunday due to the Istanbul Marathon and that alternative routes will be made available for drivers.

The closures will start in stages at 3.00 a.m. and 6.00 a.m. on Nov. 2 (Sunday) and will remain in place until the official program is completed.

The statement underlined that traffic arriving at the July 15 Martyrs Bridge and the D-100 highway will be redirected.

Early morning closures to protect race corridor

According to the statement, the first stage of closures will begin at 03.00 a.m.

At that hour, the following access points will be shut down to secure the marathon route and the bridge approaches:

  • Guney Zincirlikuyu exit.
  • Kuzey Uzuncayir ramp closure point.
  • Kuzey Unalan Atasehir Sabiha Gokcen exits the closure point.
  • Gayrettepe Melas Hotel front D-100 south access (traffic will be forced toward Yildiz Posta and Esentepe).
  • Barbaros Boulevard Zincirlikuyu D-100 south access (traffic will be forced toward Besiktas).
  • Sait Ciftci variant upper D-100 south access (flows coming from Fulya will be forced toward Sariyer),
  • Barbaros Boulevard Sait Ciftci D-100 south access (flows will be forced toward Sariyer).
  • Kisikli Avenue access from Altunizade Bridge to D-100 north.
  • Mahiriz Avenue access from Altunizade Bridge to D-100 northbound.
  • Access from Beylerbeyi Abdullahanga Avenue to the July 15 Martyrs Bridge northbound.
  • Tophanelioglu Avenue has access to D-100 north and tunnel entry.
  • Access from West Atasehir Kizil Begonya Street to the North Ring Road Ridvan Dedeoglu Viaduct.

These locations are mainly entry ramps that feed the D-100 (one of Istanbul’s main east–west roads) and the bridge line. By blocking them, the authorities aim to keep the marathon corridor free of private vehicles.

Traffic to be forced onto northern axes

For these 03:00 closures, the Governor's Office also set redirections. Traffic coming from the O-1 southern route toward the July 15 Martyrs Bridge will be completely cut and sent to the Buyukdere–Balmumcu/Levent–Sariyer separation. Flows from the Sabiha Gokcen exits will be diverted to the Camlica connection road.

Vehicles arriving from Camlica toll booths will be sent toward Unalan–Atasehir–Camlica.

Drivers in Yildiz Posta and Esentepe will be forced to follow the designated direction, while flows from Fulya will have to proceed to Sariyer.

Traffic toward Besiktas will also be compulsory.

Second phase to affect the historic peninsula and coastal roads

From 06.00 onwards, wider and more central closures will take effect. At this hour, the following roads and all streets feeding into them will be closed:

  • Rauf Orbay Avenue in both the Florya and Yenikapi directions.
  • Kennedy Avenue (the coastal road) between Unkapani and Bakirkoy in both directions.
  • Ankara Avenue and all its feeder streets.
  • Alaykoskue Avenue and all its feeder streets.
  • Alemdar Avenue and all its feeder streets.
  • Divanyolu Avenue and all its feeder streets.
  • Ragip Gumuspala Avenue in both directions between Sarayburnu and Unkapani and all its feeder streets,
  • Resadiye Avenue (Sirkeci coastal road) and all its feeder streets.
  • Galata Bridge in both directions and all access to it.
  • Eurasia Tunnel in both directions and all access to it.
  • Havuzlu Junction underpass and all access to it,
  • Sultanahmet Atmeydani Avenue and all its feeder streets.

This second group of closures covers the historical and touristic core of Istanbul, including the coastal route between Sarayburnu and Bakirkoy, the approaches to Sirkeci, the bridges that connect Eminonu and Karakoy, and the main roads around Sultanahmet.

The statement said that the Eurasia Tunnel, which links the European and Asian sides under the Bosphorus, will also be closed in both directions for the duration of the program.

Alternative corridors to keep the city moving

To prevent congestion, the Governor's Office listed several alternative routes that will stay open while the marathon is in progress. Drivers will be able to use:

  • Ataturk Boulevard
  • Balat coastal road
  • Unkapani Bridge
  • Fevzipasa Avenue
  • Vatan Avenue
  • Millet Avenue
  • Yeni Havalimani Avenue
  • Eski Havalimani Avenue
  • Ekrem Kurt Boulevard
  • D-100

These alternatives provide north–south and east–west connections around the closed zones and will allow residents, tourists, and expatriates to move without entering the marathon security perimeter.

The statement noted that traffic redirections would remain in force “until the program is completed.”
