Abu Dhabi is pressing ahead with plans to build three new tunnels in the centre of the city, with construction expected to be completed by 2009. The consultant is De Leuw Cather International, part of the US’ Parsons International.The project calls for the construction of three tunnels running from Mina Street to Salaam Street and on to Hazza bin Zayed Street in the northwest of the capital. The length of the longest tunnel will be 1,100 metres with the two smaller ones extending about 700 metres. Each tunnel will include a three-lane dual carriageway. The scheme, which is still in the design stage, is expected to go to tender in mid-2006 with one contract covering all three tunnels. Total project costs are estimated at about $170 million. The project is one of several planned in the capital to prevent increased congestion as the population begins to increase and more real estate projects come on line. The client is Abu Dhabi Municipalities & Agriculture Department.
