Construction Status

Building a single 1,386 km expressway as one contract would be unworkable — no single construction company has the capacity, and a single point of failure could stall the entire corridor. Instead, NHAI split NE-4 into more than 50 separate EPC (Engineering, Procurement, and Construction) and hybrid-annuity packages, typically 20–45 km each, and put them out to competitive tender individually. That's why completion percentages vary so widely between adjacent packages in the tables below — each one is effectively its own project, with its own contractor, award date, and construction timeline, even though together they form one continuous road.

This approach lets NHAI parallelize construction across all six states simultaneously rather than building sequentially from Delhi to Mumbai, which is the main reason sections in Madhya Pradesh and Rajasthan were able to open years before the Maharashtra coastal stretches even broke ground. It also means delays on one package — due to land disputes, monsoon damage, or contractor performance — don't necessarily block progress elsewhere on the corridor.

Construction at this scale, across varied terrain and six states, hasn't been without problems. NHAI has taken disciplinary action against contractors and officials over quality defects on parts of NE-4, and drivers have reported rough pavement on some recently-opened stretches — see our coverage of NHAI's response to structural defects and driver reports from the Kota–Jaipur section for the latest on that.
