The Reliance Gas Transport and Infrastructure Co. Ltd. is building the East-West Gas Pipeline from Kakinada to the Western state of Gujarat in India. The pipeline has a length of 1300 km and a diameter of 48 “. 11 numbers of major river crossings have to be constructed. The longest and most critical is the Gautami Godavari River Crossing with a lengths of 2400 m. Due to the lengths, the large diameter and the variable ground conditions  traditional construction methods could not be applied. The pipe jacking method has been selected. A jacking shaft has been constructed on each bank  and a receiving shaft in the center of the river. Two tunnel sections each with a lengths of approximately 1200 m and a internal diameter of 2400 mm have been constructed by using the pipe jacking method. Due to the variable ground conditions and high water pressure Dual Mode Pipe Jacking Machines were choosen. The steel gas pipeline will be prepared and pushed into the tunnel by using a newly developed pipe thruster. The annulus between the gas pipe and the tunnel will be filled with a specially developed free flowing material.
