Highway Retaining Wall System
A multi-tier shotcrete retaining wall along a highway corridor expansion, requiring soil nail reinforcement and staged construction to maintain traffic flow.
- Soil nail installation and shotcrete facing
- Drainage system integration behind wall face
- Phased construction across three tiers
- Traffic management coordination
Constraints: Active roadway, limited work windows, strict vibration limits near adjacent structures.
Design Goal: Achieve 75-year design life with minimal maintenance requirements and consistent architectural finish.
