Otoyol 6 (English: Motorway 6), named the Kınalı-Balıkesir Motorway (Turkish: Kınalı-Balıkesir Otoyolu) and abbreviated as O-6, is a planned 321-kilometre-long (199 mi) toll motorway in Turkey, with an 82 km (51 mi) section between Malkara and Lapseki open to traffic. When complete, the route will begin at Kınalı, travel south to Çanakkale, cross the Dardanelles via the 1915 Çanakkale Bridge, and terminate at Balıkesir; connecting western Anatolia with East Thrace. The route is the first motorway in Turkey outside of Istanbul to connect the European and the Asian parts of the country.
