SANGRUR, March 20 -- Punjab cabinet minister Aman Arora opened a newly constructed railway underbridge (RUB) in Sunam before formal clearance, drawing objections from the Northern Railway, which has urged authorities to keep the structure closed until completion and safety approvals are in place. In a letter addressed to sub-divisional magistrate of Sunam Udham Singh Wala, the assistant divisional engineer of the railway's Patiala division stated that while the project is in its final stages, several critical works and safety measures are still pending. The railway authorities emphasised that the underbridge must not be opened to the public until it is fully completed,. The letter warned that any forcible opening before completion could lead to unsafe conditions, adding that responsibility for any untoward incident would rest with the state government and authorities concerned. Arora could not be contacted for comments. Minister's officer on special duty Amritpal Singh said decision was taken in view of long-standing public demand. The bridge was largely complete, with only minor works such as painting remaining. htc...
