The Gebze-İzmir project is a toll motorway procured by the Turkish General Directorate of Highways under a Build, Operate and Transfer (BOT) Model. This project is the largest BOT project in Turkey up to now. It includes 420 km of motorway (2x3 lanes) between Gebze (on the North shore of İzmit Bay) and İzmir, as well as a 3,000m suspension bridge crossing İzmit bay, three tunnels with an approximate cumulative length of 6km and 20 toll stations. The project is implemented in two phases. The first phase from km 0 (Gebze) to km 58 includes the 3,000m Izmit bay suspension bridge which is one of the longest suspension bridges in the world by the length of its central span (1,550m). The level of traffic for the first phase is expected to be about 40,000 vehicles per day. The second phase includes the remaining 362 km of motorway between km 58 and Izmir, two tunnels of 1,700m and 1,020m as well as the ring road of Bursa, the fourth largest city in the country. Egis is a 50% shareholder of the operating company Gebze İzmir İşletme ve Bakım (GİİB). The other 50% are hold by the shareholders of the concession company. GİİB is in charge of the operation, maintenance and toll management of the motorway. GİİB is also in charge of pre-operational services needed for the opening to traffic of the motorway. After a first stage of definition of the operator's needs, the purchase of vehicles and equipment, the recruitment and training of staff and the development of the whole operating documentation will follow. The operation of the first phase will start at the end of 3.5 years of works at the beginning of 2016 and fully opened to traffic as of 04.08.2019
