National Capital Region Transport Corporation (NCRTC), which is building the high-speed RRTS corridor in the NCR region, has shifted to "micro tunnelling" at the busiest station sites before actual tunnel construction for utility diversion work starts. The unique technique has been employed keeping public convenience in mind. Delhi's busiest transit hub due to the presence of two Delhi Metro corridors, a railway station, and an interstate bus terminal— is also the site of the upcoming Delhi-Meerut Regional Rapid Transit System (RRTS) corridor. To ensure minimum inconvenience to a large number of travellers taking these modes of transport as this tunnelling technique is being used at these sites. Micro tunnelling is a trenchless underground construction technique generally used for constructing smaller tunnels for utility diversion, such as drainage pipelines to minimize public inconvenience caused during the construction.

Micro tunnelling helps install RCC or concrete pipelines of various diameters below highways, railroads, runways, ports, and environmentally sensitive areas without disturbing the surface activities and users. It allows free public movement in the area, therefore, mostly adopted in places where footfall is high, and trenching is not advisable as the extraction of debris causes blocking of passages — restricting movement of people. It is also helpful for preserving the existing infrastructure from any physical damage or alteration. Numerous basic utility infrastructures are also being constructed, upgraded, or relocated by NCRTC, which are infringing the alignment of the RRTS corridor. Delhi Jal Board's sewer interceptor line is one among them. Moreover, residents of NCR will benefit from this improved infrastructure for a long period of time.

Construction work at Anand Vihar is currently in full swing with the work of launching the shaft of tunnel boring machine (TBM). Two TBMs will be lowered in the launching shaft to bore RRTS twin tunnels of 6.5 metre diameter from Anand Vihar towards Sarai Kale Khan to construct around 3km of tunnels, which will be the longest section between any two mass transit stations in the country.
