2. LOCATION AND IMPORTANCE OF BRIDGE CROSSING
There are two options to pass the Izmit Bay. The first
one is around the bay which is about 90 km and the
other one is using the Eskihisar-Topçular ferry which is
a few kilometres west of the bridge site.
Under normal conditions it takes about 1 hour and
20 minutes using either option. However it takes only
six minutes to pass through Osmangazi Bridge
Crossing.

3. OPERATION OF BRIDGE
Toll collection, toll check, traffic safety, ITS (Intelligent
Transport System), traffic management, de-icing &
snow clearance, cleaning and controlled access of
Osmangazi Bridge traffic is operated and maintained
by each relevant department of GIIB within the whole
Gebze-Orhangazi-Izmir motorway system.
Osmangazi Bridge is one of the iconic structures of
Turkey and is already a strategic part of the transport
system as well as being an economic asset. It is
essential to ensure it is available for use at all times
and is safe for all users. Therefore a number of
protective security measures are taken by the Turkish
Government in addition to the design and operation
actions taken by the Concessionaire.
