Chief Minister Mamata Banerjee proposed the politically controversial realignment of the East-West Corridor from Central to Esplanade in 2012, stating that the original plan would affect 250 shop-owners and tenants in the Lalbazar and Bowbazar area. The residents and traders of those areas started protests. KMRC and JICA requested the Government of West Bengal to stick to the original plan to avoid impacting the entire project. This was the first time in the country that a metro corridor alignment was being changed after preparation of DPR and sanction of the project. Despite opposition from the official agencies, the Government of West Bengal forcefully approved the route realignment in 2013. This changed the location of Mahakaran metro station and increased the length of the corridor by . Later, KMRC said that the realignment would increase ridership and revenue by at least 30 percent.
