Shanghai - cn/51Highway Design competition for the crossing tunnel option across two river channels, 10 km and 15 km-long, at the Yangtze Estuary, to link Pudong New Area in the south and Chong Ming Island in the north, won by Shanghai Tunnel Engineering & Rail Transit Design and Research Institute (STEDI) consortium, involving Hyder Consulting. Twin bored 3-lane tubes of 14 m-diameter to be shield tunnelled, together with tunnel ventilation system and 30 m-high ventilation shaft. Consortium now hopeful for winning detailed design due to be placed in 2002. Visit www.hyder-consulting.com 44/01. The central government approved a US$1.47 billion project, involving building a tunnel, bridge and elevated highway to connect the Changxing and Chongming islands to the city. This largest ever urban project for Shanghai will see an 8.5 km-long tunnel built between Pudong and Changxing Island, which is situated to the northeast of the city. A 9.5 km-long bridge will further link the island with Chongming Island. The tunnel and bridge will then be connected by a 7 km-long elevated highway on Changxing.

The new tunnel is part of a connection to Chongming Island, including also a 10.3-km cable-stayed bridge between Changxing and Chongming islands, that will cost US$1.48 billion. The connection has a total distance of 25 km from Pudong to Chongming via Changxing Island. The 8.95 km-long 15.2 m-diameter tunnel, which comprises two parallel tubes with a combined six lanes of traffic, will be one of the largest shield-driven tunnel in the world. The project is expected to take at least five years to complete. Sitting at the mouth of the Yangtze River, Chongming Island is the third largest island in China with a total area of 1,041 km2.

It is expected to take five years to build and cost USD1.48 billion. The tunnel and bridge will extend 25.5 km, from Wuhaogou in Pudong, and across two 8.9 km parallel tunnels to Changxing Island and then over a 10.3 km-long bridge to Chenjia Town in the east of the island. Tunnel design by an international consortium including Halcrow, Shanghai Tunnel Engineering and Rail Transit Design and Research Institute, Parsons Brinckerhoff and The Third Harbour Engineering Investigation and Design Institute.
