DIAL plans elevated cross taxiway for Delhi International airport
The ECT bridges are designed to carry the weight of the heaviest aircraft
The Terminal-3 of Indira Gandhi International Airport (IGIA) will get a elevated cross taxiway (ECT) by June 2022.
The elevated taxiway will be 1.5 km long and 203 mtr wide and have a 148 mtr bridge section over the main road between T3 and Mahipalpur and a 43.8 mtr bridge portion over a road adjacent to the boundary wall of the airport.
The smaller bridge section will be on the road along the boundary wall leading to the area behind the Centaur Hotel. The main T3 road will remain at the existing level and the taxiway will be on an elevated bridge eight mtr over it.
The Delhi International Airport (DIAL) had selected Larsen & Toubro (L&T) for the current phase of expansion under which IGIA will get a fourth runway, ECT and a bigger Terminal-1. L&T has already begun the work. The ECT will cost Rs 1,400 to Rs 1,600 crore.
The ECT bridges are designed to carry the weight of the heaviest aircraft, such as Airbus A380. There will be carriageways on the sides for passage of emergency vehicles like fire tenders and tow tractors in case of a plane breaking down. According to L&T, the ECT will have two parallel taxiways, each about 1.8 km long and 44 mtr wide.
The two taxiways will be separated by a space of 47 mtr to allow for the safe passage of two passing aircraft. There will be a lane for emergency vehicles on each side of the taxiway.
The ECT will be about eight mtr above T3 road. A cargo access road is planned adjacent to T3 road. The taxiway bridge of the ECT over T3 road will span the planned cargo road width too.
