Then it was bifurcated to 215 and 520. The 215 part was suitably completed and 520 continued. The 520 part is the biggest iron ore region of Asia, without proper connectivity. As the activities increased several jams occurred due to vehicle breakdown. Owing to the intense congestion thousands lost lives or were maimed, specially those in small vehicles and motorcycles. The contractors are very lethargic and the N.H. Authority also finds it difficult to manage as it operates from Rourkela, instead of having office at Barbil or Koida the epicentre of all jams.
