(), named the Kñnalñ-Balñkesir Motorway () and abbreviated as O-6, is a planned toll motorway in Turkey, with an section between Malkara and Lapseki open to traffic. When complete, the route will begin at Kñnalñ, travel south to ÃÂanakkale, cross the Dardanelles via the 1915 ÃÂanakkale Bridge, and terminate at Balñkesir; 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.
Construction started on 18 March 2017 in ÃÂanakkale, on the 102nd anniversary of the Turkish naval victory during the Dardanelles Campaign of World War I. The Malkara-Lapseki section (~90 km), including the 1915 ÃÂanakkale Bridge, was opened on 18 March 2022.
