## Resource

As Pripyat was evacuated following the Chernobyl disaster, a Soviet pontoon bridge unit worked under extreme radiation to maintain a vital river crossing. The episode follows the high-stakes engineering and personal courage required to keep evacuation buses moving while radiation levels remained unknown.

## Highlights
- Main idea: The critical role of the PMP floating bridge in managing the mass evacuation of Pripyat
- Technical challenge: Anchoring and pinning heavy steel pontoons against a moving current to create a stable roadway
- Failure mode: The catastrophic collapse of the crossing would have stalled both evacuation buses and emergency response convoys
- Practical takeaway: Crews utilized rapid rotation windows to perform high-risk work while minimizing radiation dose
- Human element: The perspective of Igor Khiryak, a young Soviet soldier serving on the front lines of the disaster response
