The Delhi Metro Rail Corporation (DMRC) has been contracted by the Tamil Nadu government to prepare a detailed project for a metro rail system in Chennai (formerly Madras). The report, to be prepared at a cost of Rs33 million, will be completed in six months. A feasibility study was carried out by the DMRC, which recommended developing the Chennai metro along three corridors. Corridors I and II would be taken up in the first phase. The third corridor would come up later in the second phase. The first corridor will cover 31.54 km from Tiruvottiyur in the north to the airport along the arterial Anna Salai. Of this, about 8.4 km could be underground and the rest will be on elevated track. The second corridor will cover 13.54 km from Chennai Beach to Koyambedu, along EVR Periyar Salai. The third corridor will span 21.68 km from Tiruvanmiyur to Lattice Bridge Road, Ramakrishna Mutt Road, Luz Church Road, Theagaraya Road, Inner Ring Road and Ambattur Industrial Estate. The first phase of the Chennai project is estimated to cost Rs50.8 billion. It would be implemented between 2005 and 2010. Visit www.delhimetrorail.com 16/05.

National Thermal Power Corporation (NTPC) has signed a MoU with the government of Uttaranchal for the initial survey and investigation for the 3 x 120 MW Tapovan Vishnugad hydro scheme on river Dhauliganga. It is a tributary to river Alakananda which itself is a tributary to river Ganga. A 11,646 m-long headrace tunnel will be built, standard horse shoe-shaped cross section with 4.8 m diameter. The project area is located in the central Himalayan crystalline group of rocks. The rock comprises metamorphic rocks, mostly granetiferous augen gneiss, schist, quartzites with intermittent bands of schist and basic rocks. It is expected the headrace tunnel will mainly encounter this type of rocks. Presence of hot water springs of nearly 80-100°C in nearby areas and in the drilling activities along the Main Central Thrust (MCT) areas. Not much exploration drilling is possible along the tunnel alignment which will be covered with a 1 to 1.5 km overburden. The horizontal cover is also very thick. The tunnel alignment is covered with snow and thick forest areas of rugged topography. The zone may not be suitable for geophysical exploration due to the difficult topographic condition. Vertical drilling may result unnecessary, long and difficult. The planned method of construction is drill/blast with rockbolts, shotcrete, wiremesh and steel arches (I and H sections) as support. Final concrete lining. Date to invite tenders not decided yet. Detailed survey and investigation started as of 1st January, 2003. Estimated cost Rs5.55 billion (value 1992) to be revaluated 9.5% approximately per year. Self financing by NTPC for survey and investigation.

Prime minister Atal Bihari Vajpayee announced on 24th March that the Rs5 billion Rohtang tunnel project had been approved and decks had been cleared for starting the execution of the project in April 2002. The 9 km tunnel will be driven under the 4,000 m-high Rohtang pass, providing all-weather road to Lahaul-Spiti and Laddakh. 14/02.Prime Minister Atal Bihari Vajpayee laid the foundation stone of the 9 km Rohtang tunnel near Solang Nallah, on the Manalli-Leh road, considered to be the highest road link on earth. Project executed by Border Roads Organisation (BRO). 22/02.The Border Roads Organisation (BRO) has signed a contract with SMEC International for the project's design of the 9 km Rohtang tunnel. Once the detailed report is ready, work will begin early next year on boring the tunnel to connect the Kullu valley to the snowbound Lahaul valley by an all-weather route instead of the present route through the 3,980 m-high Rohtang Pass that remains under snow for more than half of the year. The tunnel will also provide a better route to the landlocked Ladakh region in Jammu and Kashmir. Overlooking the popular resort town of Manali, the Rohtang tunnel will be located at around 2,900 m and will reduce the distance of the 480 km Manali-Leh road by 46 km. The environment clearance for the project has already been obtained. The BRO has already built 24 km of approach roads leading to both portals of the tunnel. The work on the tunnel is expected to finish by 2014. Read E-News Weekly 16/2005. Visit www.smec.com.au 28/06.

The Border Roads Organisation has awarded the EUR250 million contract to build the 8.8 km-long Rohtang Pass Highway Tunnel to the JV Strabag AG (Austria)/Afcons (India). At 3,980 m, Rohtang Pass, in the western Himalaya region of northern India, is one of the highest navigable mountain passes in the world. The Leh-Manali Highway, the only road connection to the northern border of Himachal Pradesh province, leads over Rohtang Pass. The heavy winter snowfalls and storms in the region mean the communities north of the pass are cut off for 4-6 months when the road is closed. The construction of the Rohtang tunnel, at approximately 3,100 m above sea level, will make the Leh-Manali Highway passable year-round and will contribute significantly to the economic development of the northern border region.Special challenges in building the tunnel include the elevation, the extreme climate and the geologic conditions. The rock at the site consists mainly of slate and migmatite, with three potential fault zones and squeezing rock, making NATM the method of choice.The horseshoe-shaped tunnel will be 10 m wide, to accommodate an 8 m-wide two-lane roadway plus a 1 m-wide walkway on each side. A 2.25 m-high and 3.6 m-wide escape tunnel will be integrated underneath the main roadway in the tunnel cross section. In all, the works will involve moving more than 800,000 cu m of rock. Tunnelling will begin in Spring, 2010 and will proceed from both portals. As the northern portal will not be accessible during the winter months, the main tunnelling works will be focused at the southern end. With a planned construction time of about 5.5 years, the tunnel should be completed by end-2015. Visit http://bro.nic.in, www.strabag.com and www.afcons.com. 43/09.
