The Delhi Metro’s un­der­ground con­struc­tion in its third phase of ex­pan­sion can­not be con­sid­ered any­thing short of a revo­lu­tion. Close to 80 kilo­me­tres of un­der­ground tun­nels have been laid be­neath the city in the last five years with­out caus­ing any dis­rup­tion to the din and bus­tle of the daily life above.

The sheer enor­mity of the task can be gauged from the fact that, the to­tal length of the un­der­ground cor­ri­dors in Delhi Metro’s Phase-3 is more than the to­tal un­der­ground sec­tions built by DMRC in both Phases 1 and 2, mak­ing it one of the most chal­leng­ing con­struc­tion phases for the or­ga­ni­za­tion.

Com­bin­ing the first two phases, Delhi Metro has a to­tal of 31 un­der­ground sta­tions, while Phase-3 alone has 35 un­der­ground sta­tions. The to­tal length of the un­der­ground cor­ri­dors in the first two phases was 48.06 kilo­me­tres and Phase-3 alone has un­der­ground cor­ri­dors of 54 kilo­me­tres. The first phase of Delhi Metro’s con­struc­tion had 13.17 kilo­me­tres of un­der­ground Metro lines while the sec­ond phase had 34.89 kilo­me­tres.

The de­ci­sion to con­struct more un­der­ground cor­ri­dors was taken to en­sure that the con­struc­tion work caused min­i­mum in­con­ve­nience to the peo­ple. By con­struct­ing so many un­der­ground stretches, DMRC has also avoided caus­ing any dam­age to the ex­ist­ing in­fra­struc­ture such as flyovers and roads.

For the first time in the his­tory of Delhi Metro’s con­struc­tion, four dif­fer­ent tun­nel­ing stretches in Phase-3 have passed be­low ex­ist­ing un­der­ground Metro stretches in the city. These four un­der­ground stretches are:
