Reconstruction of the 27-year-old Jawaharlal Nehru Stadium will miss the Dec 31 deadline and the venue for the opening and closing ceremonies of the 2010 Commonwealth Games would need three more months to get ready because a newly proposed tunnel has to be built.

The 150-metre-long tunnel, which will open up at the centre, has been designed to connect the two ends of the stadium. The tunnel will be used by the performers to enter the ground during the ceremonies.
