Context

Coastal corridors play a critical role in local mobility, commerce and community access. These routes face continuous exposure to rainfall, runoff, erosion and changing weather conditions. When drainage systems underperform, communities experience flooding, restricted movement and increased safety risks.

The National Works Agency manages coastal infrastructure that supports both residents and visitors. Improving these assets requires coordinated engineering, reliable project oversight and structured delivery to ensure that works reduce environmental vulnerability without disrupting community activity.

Our Approach

Rhoden Group delivers coastal infrastructure upgrades through a structured civil engineering model. The approach begins with site assessments that examine road conditions, water flow patterns and areas at risk of erosion or runoff impact. This informs the engineering design and construction planning required.

Our teams manage:

  • Excavation and grading for improved surface durability
  • Installation of reinforced drainage channels
  • Reconstruction or resurfacing of compromised road segments
  • Water flow management and outfall improvements
  • Traffic coordination to maintain community access
  • Quality controls to protect long term asset performance

The work is delivered in close coordination with local authorities to support users throughout construction and minimise disruption.

Impact

Upgraded drainage systems and reinforced road surfaces reduce the frequency and severity of flooding during heavy rainfall. Improved road durability enhances safety, supports uninterrupted travel and strengthens community resilience. By modernising critical sections of coastal routes, Rhoden Group helps safeguard essential economic and social connections.
