The present approach to the airport from the Millennium city is a highly congested one through the National Highway-8, also known as the Delhi-Gurugram Expressway. An under construction ‘Dwarka Expressway’ will act as a by-pass of NH-8 from Gurugram to Dwarka. The plan finalised now is to build a 4-km tunnel road from the Dwarka Expressway straight to the T3 terminal of the Delhi Airport. This deep 4-km long tunnel for vehicles is proposed to run along the alignment of the existing underground Delhi Airport metro line from T3 Terminal to Dwarka Sector 21 Metro station. Passengers destined for the International airport from Gurugram by 2020 will be able to take Dwarka Expressway and then the tunnel road to reach the airport, bypassing the entire NH-8 road. Residents of the bustling Dwarka area will have the same faster option. The technical consultant to be engaged for the project has been asked to advice on the feasibility of the said tunnel and other pre-construction activities like having its junction with Dwarka Expressway. The tunnel, one built, will offer “western connectivity” to the International Airport.
