The contractor engaged by Delhi Metro Rail Corporation has begun test piling on the north-western side of the North overbridge.

This is prior to piling works to be undertaken to rebuild the two-wheeler bays of the bridge into wider portions. “Non-working piling is on in an independent area, away from the new bridge's alignment. The portion that would be rebuilt would be 1.5 metres wider than the side bays being demolished,” said an engineer at the work site.

The dismantling of the bay on the northern side is getting delayed because the Kochi Corporation has been unable to complete repair works over the Chittoor Road on time.

The plan is to rebuild the two side bays as single lane stretches in another nine months. Vehicles would be diverted through them, following which the main carriageway would be pulled down. This portion will be rebuilt in another nine months.

The deadline for the Rs. 70 crore project would expire in another 18 months. The new bridge would have a gradient ratio of 1:20, making it less steep than the existing bridge which has a ratio of 1:14 (one metre height for every 14 metre length).

A DMRC official said that the agency has obtained the nod from the Railways to dismantle the side bay on the bridge's southern side, over the railway portion. The approach ramps on either side of the bay were dismantled earlier this month. “We would have to coordinate with the Railways and pull down the portion when there is no rail traffic.”

Referring to the proposal to widen the narrow North bridge-Madhava Pharmacy Junction stretch into a four-lane road, he said that the agency is ready to execute the work.

“We have already awarded the contract. Land has to be acquired and handed over to us. The bottlenecked free-left turn towards MG Road would be widened alongside the widening works on M G Road up to Jos Junction,” he said.

The tender to widen MG Road was cancelled since executing the work alongside the widening of the North bridge and Banerjee Road would cause traffic hold ups. “We would widen MG Road (by another two metres on either side) and the Jos Junction-South Railway Station stretch into four-lane roads, alongside work on the metro-rail.”

Encroachments on the stretches too would have to be removed. Work on the Salim Rajan Road flyover will be over in another 14 months.
