Delhi Metro

To be completed in four phases, this 152-mile (244-kilometer) mass transit system will bring a much-needed sustainable and viable means of transportation to India`s Delhi residents. As part of an international consortium of consultants, WSP | Parsons Brinckerhoff began providing general engineering consulting services to the Delhi Metro Rail Corporation in 1998. Phase I of the system was completed in November 2006, and it consists of three lines with a total length of 40 miles (65 kilometers) and 59 stations—incorporating underground, at-grade, and elevated sections. WSP | Parsons Brinckerhoff completed its services for Phase II in 2010, which added an additional 75 miles (121 kilometers) and 81 stations to the Delhi Metro Network, including a 12-mile (19-kilometer) Airport Express Line.
