how did crews reopen prithvi highway?

Crews reopened the Prithvi Highway at the Krishnabhir section by constructing a 300-meter emergency track. They initially opened 50 meters of the track while also exploring long-term solutions such as tunnels and soil nailing to stabilize the area. After a successful trial run, the highway was reopened to two-way traffic on September 16, 2026, effectively ending the blockage. The reopening was contingent on no new landslides occurring, which was closely monitored.
