Lalbaug Flyover, which was shut for commuters till Monday, after a gap surfaced on it, has now developed another gap near the ITC, Parel end.
The traffic police had shut the flyover for the north-bound (CST to Parel) commuters after the first gap was noticed on Thursday. The traffic was opened on Friday after the Brihanmumbai Municipal Corporation (BMC) carried out some temporary repairs, however, after new gaps surfaced on Monday, the area was barricaded by the traffic police. This affected the south-bound traffic.
When inquired about the new gap, civic officials said that they were aware of the loosened concrete near the ITC section of the flyover and would soon take up the repair work. “We did not receive traffic permission to carry out work near both the joints at the same time (Chinchpokli and ITC). We will soon undertake the repair works,” said an official from bridges department.
The civic body is yet to carry out a detailed study on the other 69 joints across the 2.45 km long Lalbaug flyover.
Meanwhile, officials in the civic body said that seals between two of the bridges’ expansion joints had slipped, leading to the development of the gaps on the flyover. Expansion joints allow continuous flow of traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced concrete.
“The flyover did not develop cracks. The rubber seal between two expansion joints has come loose. The same contractor will undertake the repair work as it is within the defect liability period and we are expecting to finish the work by Sunday,” SO Kori, chief engineer (bridges), had said earlier.
The Lalbaug flyover had its own share of problems even before it was thrown open to public
- Earlier, in 2010, while the construction of the flyover was underway, a cantilever of the flyover had collapsed and fallen on three cars and a motorbike, injuring one person.
-Then soon after the flyover was opened to traffic in June 2011, it developed potholes, for which the MMRDA slapped a fine of Rs 5 lakh on the contractor, Simplex Infrastructure.
-A year later, in 2012, a concrete block from a non-structural component of the flyover collapsed on the junction below it. No one was injured.
- After repeated accidents, MMRDA had slapped a show cause notice to the contractor.
