🛠️ Project Overview
Bastion Group was engaged to assess and eventually replace a deteriorating rural bridge structure on Jumpin Run Road near Andrews, South Carolina. The project began with an in-depth forensic analysis following visible signs of structural aging and increased anticipated loading from nearby development activity.
🔍 Phase 1: Structural Forensics & Emergency Rehabilitation
Initial investigations revealed multiple degraded timber piles compromising the bridge’s load-carrying capacity. Despite the absence of original as-built drawings, Bastion engineers confirmed that the deck system had been supporting truck traffic equivalent to HS-20 highway load standards.
Bastion performed immediate field interventions including:
- Scanning and coring of the existing deck
- Installation of pressure-grouted piles into bedrock
- Custom bracket-and-sleeve systems to support deteriorating bent caps
- Reinforcement of exposed elements to resist further corrosion
🧱 Phase 2: Full Replacement Design
In parallel, Bastion was retained to provide a design-build proposal for full bridge replacement. This phase includes:
- Demolition planning for the existing span
- New superstructure and substructure design
- Foundations engineered for modern traffic loads
- Permitting and coordination with local authorities
✅ Value Delivered
This project exemplifies Bastion Group’s dual strengths in rapid forensic response and infrastructure redevelopment. From emergency pile remediation to long-term bridge replacement design, our team ensured the safety of the traveling public while preparing for the region’s growth and increased vehicle demands.
