VIDEO: Kolin-Kalyon and Limak-Cengiz win North Marmara connector tenders

May 23, 2016
Turkey has awarded the much-delayed tenders for the motorway connector roads to Istanbul’s Third Bosphorus Bridge.

The 90km motorway section between Kinali and Odayeri was awarded to the Kolin-Kalyon joint-venture with completion in seven years and nine months, according to Turkish media reports. The 170km section between Kurtkoy and Akyazi was awarded to Limak-Cengiz joint-venture which will finish the work in six years and nine months.

The tenders were part of the 260km North Marmara Motorway project that includes the soon to be completed Yavus Sultan Selim Bridge. The Northern Marmara Motorway will, when completed, flow around the northern sections of Istanbul, the country’s financial centre.

The highway will cross the Bosphorus Strait over the Yavuz Sultan Selim Bridge and serve as the outermost beltway of Istanbul. The route runs from Kınalı on the European side to Akyazı on the Asian side. Importantly, the eastern end of the motorway will connect with the Otoyol 4, also known as Anadolu Otoyolu or Anatolia Motorway. The O-4 is a toll motorway connecting the northeastern Marmara Region to the Central Anatolia Region, including the capital Ankara.

The four-lane Third Bosphorus Bridge, now officially the Yavuz Sultan Selim Bridge, is a 2.2km cable-stayed and suspension crossing for rail and motor vehicles. The longest span is just over 1.4km and width is 58.4m. The bridge sits between Garipçe in Sarıyer on the European side and Poyrazköy in Beykoz on the Asian side. Work started in May 2013 and completion is expected later this year.
