The steel spans are massive structures, consisting of beams made of structural steel. These are installed to connect the pillars in some complex areas where the corridor is crossing rivers, bridges, rail crossings, metro corridors, expressways or other such existing infrastructure, it is practically not possible to maintain this distance between pillars.
