This helipad is now being improved to facilitate landing of Dhruv helicopters. The Army also constructed two helipads at Gauri Kund.
A heli-bridge was created at Govind Ghat to transport pilgrims across the Alaknanda River. Helicopters performed shuttle service from either banks of the river as the temporary crossing made earlier had collapsed.
The Army also operationalised the foot track between Govind Ghat and Lambagar on Badrinath road.
Another column conducting road clearing operations from Badrinath to Lambagar successfully launched a foot bridge over Alaknanda this evening, thus opening the foot route from Badrinath to Govindghat.

The first C 130J aircraft landed at Dharasu (a landing ground only 1300 feet long) in the early morning on Saturday for the first time despite inclement weather.
On landing the massive aircraft defueled 8000 litres of fuel into an empty bowser which was airlifted yesterday from Sarsawa by a Mi 26 helicopter.
With the availability of additional fuel now at Dharasu, the extraction, evacuation and rescue operations have picked up pace and the available helicopters are now able to make more number of trips.
Apart from the carrying fuel to Dharasu, the first C130 J on its return trip carried about 40 and the second about 100 injured and stranded pilgrims to the safer plains of Air Force Station Hindan.
An emergency medical centre has been set up at Air Force Station Hindan for the medical check-up of all the arriving tourists for immediate attention.
The first two C 130J aircraft carried fuel to Dharasu while the third is carrying a Medical team of the IAF to attend to sick people at Dharasu itself before they are moved out to safer place.
Having paved the way for fixed wing aircraft landing at Dharasu, the IAF pressed its An 32 aircraft also into action.
These aircraft are carrying Disaster Communication equipment vehicle, some more aviation fuel, Sudan pumps for refueling the helicopters and 4,200 kgs of bridging equipment of BRO.
The heavy lift Mi 26 helicopter will also be airlifting the heavy equipment of BRO to facilitate road repair and construction work.
While the fuel bridging has given impetus to rescue operations, increased flying activity in the narrow valleys is posing a new challenge to traffic management and safe flying.
The IAF has inducted additional personnel to ensure smooth planning, coordination and execution of flying operations, be it Air Force, Army or civilian operators.
Since Saturday since morning, till 3 o'clock in the afternoon, the IAF said it flew about 149 sorties in which 26,700 kgs of load and 1,355 passengers were airlifted.
In all, the IAF towards 'Op Rahat', has flown 768 sorties in which 1,03,350 kgs of load has been dropped or landed and 5,347 passengers airlifted.
