Which of the following statements regarding construction of Rohtang tunnel is NOT correct ?

The Atal Tunnel (formerly Rohtang Tunnel) is located at an altitude of approximately 3,000 metres (roughly 10,000 feet) above Mean Sea Level, not 5,000 feet [3]. Specifically, the South Portal is at 3,060 metres and the North Portal is at 3,071 metres [1]. Statement 2 is correct as the tunnel provides all-year connectivity to the Lahaul and Spiti Valley, which was previously cut off for six months due to heavy snow [1]. Statement 3 is correct as the project was executed by the Border Roads Organization (BRO) [3]. Statement 4 is also correct; the tunnel reduces the distance between Manali and Leh by approximately 46 to 50 km, significantly cutting travel time [3]. Therefore, the statement regarding the 5,000-foot altitude is the incorrect one.
