Big Lapse? Escape Route Was Planned For Uttarakhand Tunnel, But Not Built

Over 160 hours since 41 workers got trapped in a tunnel in Uttarakhand, a map has emerged that points to an alleged serious lapse on the part of the company involved in its construction. According to the Standard Operating Procedure, all tunnels over 3 km long are supposed to have an escape route to rescue people in case there is a calamity. The map proves that such an escape route was also planned for the 4.5 km Silkyara tunnel, but never executed.
