After a day of brickbats from the Commonwealth Games Federation honchos who have said conditions in the Village don't meet standards,there was more trouble for the Suresh Kalmadi-led organising committee when a foot overbridge near the main venue Jawaharlal Nehru Stadium collapsed on Tuesday afternoon,injuring 23 workers. Some workers at the site,unofficial reports put the figure at five,have been seriously injured and taken to the Safdarjung Hospital and the AIIMS Trauma Centre. The incident occurred at 3.10 pm in the Lodhi Road area of South Delhi,police said. The 95-metre long bridge was being built along with another overbridge at a cost of Rs 10.5 crore by the Chandigarh-based company PNR Infra,Delhi government sources said. The Public Works Department of the Delhi government,which had given the contract to PNR Infra for constructing the overbridge has ordered an inquiry into the incident. The bridge was to be completed soon and would have connected the parking lot of the Jawaharlal Nehru Stadium where the opening and closing functions of the Commonwealth Games would be held. Fire department officials said the labourers were putting a concrete mix at a portion of the bridge when the incident took place. PWD Chief Engineer Rakesh Mishra admitted the incident was a "setback" but expressed confidence that the project would be completed before the Games that start on October 3. Yesterday,two police personnel,including an officer,had suffered injuries when a canopy erected at the stadium fell on them.
