Impact of Heavy Rain and Floods on Transportation Infrastructure

This report details the severe impact of recent heavy rains and floods on key transportation routes in Vietnam, specifically focusing on National Highway 1 and various mountain passes in Lam Dong and Quang Tri provinces. The primary concern is the disruption of traffic flow and the urgent need for remediation efforts to ensure safety and connectivity.

1. National Highway 1: Traffic Congestion and Control Measures

• Main Topic: Severe traffic congestion and control measures implemented on National Highway 1 due to heavy rains and floods.
• Key Points:
  • National Highway 1 is experiencing significant blockages in several locations across central provinces.
  • The traffic police in Khanh Hoa province have established checkpoints to manage traffic flow from the south.
  • Specifically, three checkpoints were set up on National Highway 1 in the former Ninh Thuan province area, commencing at 2 PM yesterday.
  • Traffic police are directing vehicles only up to the Cam Ranh area, allowing them to continue their journey.
  • Long-distance vehicles are instructed to stop by the roadside and are not permitted to proceed beyond the checkpoint in Thuan Bac commune.
  • This restriction is due to severe flooding in the Cam Ranh and Cam Lam areas of Khanh Hoa province.
  • Allowing vehicles from the south to continue north would exacerbate congestion and overload the northern part of Khanh Hoa province.
• Argument/Perspective: The restriction on traffic heading north of Khanh Hoa province is a necessary measure to prevent prolonged and overwhelming congestion until weather and traffic conditions improve and ensure safety.
• Duration of Measures: These traffic restrictions will remain in place until weather and traffic conditions are deemed safe.

2. Lam Dong Province: Landslides and Road Closures

• Main Topic: Serious landslides on mountain passes in Lam Dong province, leading to road closures and urgent repair efforts.
• Key Points:
  • Heavy rains have caused severe landslides on several mountain passes in Lam Dong province.
  • Mimosa Pass and Bren Pass are currently completely closed.
  • Deputy Prime Minister Ho Quoc Dung inspected the flood situation and directed remediation efforts in Lam Dong province this morning.
  • He emphasized the urgency of clearing the routes to ensure smooth traffic flow.
• Specific Examples/Case Studies:
  • Mimosa Pass (National Highway 20): A landslide at km 2260 has caused roadbed failure, a road surface collapse, and a deep pit tens of meters in depth. The affected section has a length of approximately 70 meters and a depth of 40 meters.
  • Bren Pass: Half of the roadbed at km 22400 on Bren Pass, in the direction from Da Lat to Ho Chi Minh City, has collapsed and subsided.
  • Bren Pass (Additional Risk): Four other points on this pass are at high risk of future landslides.
• Methodology/Framework:
  • Construction units are currently building a temporary road to reopen the pass as soon as possible.
  • Deputy Prime Minister Ho Quoc Dung instructed the Ministry of Construction, Lam Dong province, and relevant units to mobilize maximum personnel and equipment for urgent repairs.
  • He also called for long-term solutions to be identified.
  • Short-term Goal: Reopen Mimosa Pass within the next 10 days.
  • Long-term Strategy: The Ministry of Construction is to assist the province in engaging experts and consultants to thoroughly study the causes of the landslides (e.g., the specific cause of cracking on Bren Pass) and develop both immediate and long-term remediation plans.
• Government Support:
  • Water levels in Lam Dong have receded.
  • The Deputy Prime Minister urged the province to quickly assess damages to support affected residents.
  • The central government has allocated 200 billion VND in emergency aid to Lam Dong province.
  • Localities are required to submit support plans and disburse funds within one week to enable residents to restore their lives and reinvest in production.

3. Ho Chi Minh Road (Western Branch): Severe Damage and Remediation Needs

• Main Topic: Significant damage and landslides on the Western branch of the Ho Chi Minh Road in Quang Tri province following prolonged heavy rains.
• Key Points:
  • The section from km 0 to km 210 has suffered severe damage to both cutting slopes (taluy dương) and embankment slopes (taluy âm) due to landslides.
  • Even in areas that have been repaired, soil and rocks can easily fall onto the road surface during heavy rain.
  • Road shoulders have eroded deeply, and drainage ditches are damaged, posing a risk to traffic safety.
• Methodology/Framework:
  • Although the route has been reopened, urgent long-term solutions are needed to ensure the safety of people and vehicles.
  • Immediate Action: For landslides on cutting slopes (taluy dương), personnel, equipment, and machinery have been deployed to clear one lane to ensure timely traffic flow.
  • For Embankment Slope and Drainage Issues: The unit is prioritizing traffic safety by installing barriers, warning signs, and deploying personnel for 24-hour traffic management.

Synthesis/Conclusion:

The current heavy rains and floods have caused widespread damage to critical transportation infrastructure across Vietnam, leading to significant traffic disruptions and safety concerns. National Highway 1 is experiencing severe congestion, necessitating traffic control measures. Mountain passes in Lam Dong province, such as Mimosa and Bren, are closed due to landslides, with urgent efforts underway to reopen them and implement long-term solutions. The Western branch of the Ho Chi Minh Road in Quang Tri province also shows extensive damage from landslides, requiring immediate and sustained remediation to ensure safe passage. The government is providing emergency financial aid and urging local authorities to expedite support and recovery plans for affected communities. The overarching priority is to restore traffic flow, ensure safety, and support the livelihoods of the people impacted by these natural disasters.
