Current Road Situation
The flood damaged major roads, bridges and mountain access routes in Rasuwa, Nuwakot and along the Trishuli corridor.
Prithvi Highway — Krishnabhir
Flood-related erosion caused a major section of the Prithvi Highway to collapse toward the Trishuli River. Reports described roughly 70 metres fully collapsed and about 120 metres severely cracked. By 4 September, the Department of Roads had started cutting a temporary bypass track above the damaged section.
Main Affected Corridors
| Route | Status through 4 Sep | Advice |
|---|---|---|
| Prithvi Highway at Krishnabhir | Severe collapse; bypass work underway | Use official diversions |
| Betrawati–Mailung–Syabrubesi–Rasuwagadhi | Multiple damaged sections | Confirm full route |
| Syabrubesi–Rasuwagadhi | Serious flood damage | Do not assume normal access |
| Galchhi–Trishuli corridor | Partial restoration with ongoing works | Expect delays |
Bridge Damage
Preliminary assessments reported extensive motorable and suspension-bridge damage. Bailey-bridge locations have been identified and international partners have pledged modular bridge support.
Kathmandu Supply Routes
The Krishnabhir closure disrupted a major supply corridor into Kathmandu, forcing fuel, goods and passenger traffic onto alternative routes.
Travel Safety
- Check the route immediately before leaving.
- Do not travel around barriers.
- Avoid unnecessary night travel on affected mountain roads.
- Never cross flooded road sections.
