No median cuts, surface intersections on future high-speed NH corridors: NHAI

NEW DELHI: New access-controlled high-speed national highway corridors will have no median (divider) openings and no at-grade (surface level) intersections, a move that aims at eliminating conflict points and reducing crashes.It has also been mandated under new NHAI guidelines issued on Monday that these corridors won’t have raised concrete dividers but flush medians — painted centre lanes with thick wire ropes or crash barriers. These will also have advance exit signage at 5 km, 2 km, 1 km and 500 metres to help motorists prepare for lane changes well in advance.The design provisions are aimed at improving safety on access-controlled corridors where cars are allowed to travel at speeds of up to 100 kmph.
