Ninety percent of work has been completed on the Pontoon bridge over the natural pond near the Baghjan 5 oil well site in Assam's Tinsukia, according to officials.

The Indian Army has been requested by Oil India Limited (OIL) to build the bridge so that the experts can approach the fire from two sides, one the original one and this is the second one over a wetland.

Indian Army has constructed the bridge for an alternative route to reach the well as they need several roads to control the gas well fire.

General Officer Commanding of 3 Corps Lt Gen Rana Pratap Kalita along with other senior officers of the Army visited the site of the gas well fire tragedy at Baghjan in Assam on Friday to monitor the progress of the work to cap the well.

The Army is part of a multi-agency effort to cap the Oil India Limited's well in Assam's Tinsukia district.
