GURUGRAM: NHAI officials have refuted claims that a new crack has developed on the Hero Honda Chowk flyover, saying that they are only carrying out repair work to mend the damage to the flyoverin April, according to the recommendations of the IIT-Bombay researchers.

The Jaipur-Delhi carriageway of the flyover was shut on Monday and the repair work will continue for at least seven days.

Repair work under way on HH Chk flyover but NHAI denies new crack

After a chunk of concrete fell off the Delhi-bound flank of the flyover in April, contractor Valecha Engineer Limited, which built the flyover and is in charge of its maintenance, had done a patchwork to cover up the crater and also sought a report from IIT-Bombay.

The report, saying that the damage to the flyover was a localised issue and nothing serious, was submitted on Sunday, prompting Valecha and NHAI officials to plan the repair work on the Hero Honda Chowk flyover.

As the damage was due to “localised concrete distress”, Valecha rennovated the deck by removing concrete slabs of size of 3.2×5.8m and replacing them with M50-grade concrete (reinforced concrete segments) on Sunday, when traffic was lean and hence, traffic congestion could be avoided.

Ashok Sharma, general manager (technical) and project director, NHAI (Gurugram), said, “No other type of damage except the aforesaid crater has been noticed on the Hero Honda Chowk flyover. The entire structure is otherwise safe. To avoid traffic congestion, one lane of the flyover has been left open for traffic movement while the other three affected lanes have been closed and will open to traffic seven days later after the newly laid concrete segments have gained the required design strength.”

The contractor has already carried out safety audits for pedestrian and traffic movement on the flyover.

The eight-lane, 1.4-km-long flyover was constructed as part of a three-layer crossing — flyover, underpass and existing roads — at Hero Honda Chowk. The construction of the Rs 197.84 crore project began in November 2014. It was expected to be completed by May 2017. However, there were delays in getting clearance for the land required for the project due to litigation and lack of coordination between departments and the flyover was finally opened in July 2017.
