The transit project, spanning 882.21 km, was launched in April, 2008 by the erstwhile Congress-led UPA government as part of the ‘Look East’ (now Act East) policy.
The route, which was initially scheduled to be completed by 2014, will bring the NE region closer to Kolkata by half the existing distance. Of the 87.51 km stretch of the project to be constructed within Mizoram, 84.19 km has been completed so far.
