ABSTRACT
ABSTRACT: Gebze-Orhangazi-Izmir Motorway (Izmit Bay Crossing and Connection Roads) is one of the most important transportation infrastructure projects in Turkey. The South Approach Viaduct is located on an important part of Gebze-Orhangazi-Izmir Motorway Project and south of Izmit Bay Suspension Bridge. The project location crosses North Anatolian Fault and it lies on the secondary fault zone because of this, different approaches are implemented for the design and the construction of the Viaduct. This paper outlines briefly the design criteria, the construction methodology and application stages of project; which is quite different from the traditional methods.
