Arch bridge: 3 coming up

The Public Works Department doesn’t seem to have learnt its lesson. Even as the PWD explores ways to rebuild the pedestrian bridge that collapsed a fortnight before the Commonwealth Games began, three new bridges of the similar design are coming up in east Delhi.
UK-based company Macalloy Bar and Cable Systems has offered to provide a modified design of the parts that gave in earlier. While the construction agency is still contemplating accepting the new design, it has already procured suspenders and bars from UK-based firm Freyssinet for the new bridges being built at Ghazipur flyover.
“The construction is being done under the direct supervision of the company’s engineers,” said SC Chauhan, PWD’s project manager.
The collapse of the under-construction bridge had caused huge embarrassment to the Delhi government. The pin of a suspender connecting the bridge’s walkway with the rainbow-shaped arch had snapped leading to the collapse.
The PWD has yet to initiate action against the contractor of the collapsed bridge. It has, however, started talking to the company that provided the suspenders and pins to modify the design of the joints and rebuild the collapsed bridge and another just a couple of hundred metres away but was left partially built after the collapse.
Meanwhile, PWD engineers said they have modified the construction strategy and are taking utmost care to ensure that the three upcoming bridges do not meet the same fate.
“The construction module has been properly defined. We are first creating the support and will then construct the arch and the deck,” Chauhan said.
The three pedestrian bridges — with 66-metre width — are coming up east, west and north of Ghazipur flyover on NH 24 in east Delhi. While one pedestrian bridge near Ghazipur village, on Road No. 56, is likely to be complete by May 31, the other two pedestrian bridges are expected to be opened for public by June 15.
