Amid reports raising questions on why under-construction Silkyara tunnel in Uttarkashi did not have a separate escape tunnel, the government on Wednesday said a separation wall was provided in the tunnel with egress openings at regular intervals that could be used as an escape route during an emergency. The 41 workers, who were trapped in the tunnel from November 12, were rescued on November 28.
In a written reply to a question in the Rajya Sabha, Union Road Transport and Highways minister Nitin Gadkari said, “In the Silkyara bi-directional tunnel on Dharasu-Yumunotri highway (NH-134), a provision of separation wall has been provided at the centre of the carriageway along with egress openings at an average interval of 565 metres for vehicular crossover and at an average interval of 300 metres for pedestrian cross passage for escape purposes during the emergencies.” Gadkari was asked whether the government has conducted a probe as to why Navayuga Engineering Company Ltd (NECL) did not build a rescue route, as is the norm in tunnel construction.
