A new road asset with multiple challenges.
The motorway was built and commissioned in several phases between April 2016 and August 2019. The first 58 km of the road was opened in June 2016 and includes the Osmangazi Bridge, a 3,000 m suspension bridge crossing İzmit Bay, which is currently the 4th longest in the world in terms of central span.
The last section, stretching 184 km, was introduced into operation in August 2019.
The toll motorway includes 20 tolling plazas and three tunnels with cumulative length of more than 6 km. The key task following construction completion was to set up a sustainable organization able to maintain and operate the 426 km of motorway, tunnels and bridge to high standards. This means fast incident response, world-class traffic management and optimal infrastructure maintenance.
