The bridge developed cracks yesterday and the wheel of a state transport bus got stuck in it. Though a mishap was averted, a portion of the bridge caved in, they said.
Meanwhile, works were underway to repair the ancient bridge. The national highways authority has now commenced works to mend the bridge. The supporting structures at the bottom are being strengthened, officials said.
Tamil Nadu Fisheries Minister K A Jayapal, Nagapattinam District Collector S Pazhanisamy and other officials inspected the bridge today.
Heavy vehicles to Karaikal and Nagapattinam ports, PSU oil establishments in Nagapattinam region, tourist vehicles to Poompuhar, Tarangambadi and Velankanni are passing through this bridge. The damage to the bridge has forced vehicles to take a circuitous route to reach these places.
Since 2009, the Highways Authority had been constructing several supporting structures at the bottom portion to prevent it from collapsing.
