Thrumshing La

[6] The pass is often closed during winter due to heavy snowfall, shutting off land communication along the Lateral Road.

At the highest point, travelers leave prayer flags in thanks for safe arrival to the pass.

[2] In a matter of hours, eastbound travelers descend the pass southward along the Lateral Road from elevations of nearly 3,800 metres (12,500 ft) to just 650 metres (2,130 ft), transitioning from alpine forests into semi-tropical orange producing valleys.

[7] Because of the many nearby hazards and frequently dangerous conditions at Thrumshing La itself, the Government of Bhutan has approved and begun constructing a bypass to the Lateral Road as part of its Tenth Five Year Plan.

The bypass will cut travel time, distance, and danger by avoiding Thrumshing La.
