2026 ACEC-NH & NHDOT Technical Exchange Conference

Session 1A: Restoration of the Elizabeth River Lift Bridge
Speaker: Amanda Ruyack & Bryan Seitz, Hardesty & Hanover
- The Elizabeth River Lift Bridge was constructed in 1958 and provides a vital rail link across the intercoastal waterway in Virginia. In June 2024, rail service was disrupted when a vessel struck the bridge’s approach truss that is adjacent to the vertical lift span. The approach truss was severely damaged and dislocated. The lift span tower, which is supported by the approach truss, was displaced. The emergency response, design e,orts, and repairs were expedited with LiDAR surveying and the creation of a 3D digital twin model, allowing for rail service to be restored in just 5 months.

Session 1B: Hinsdale-Brattleboro Construction Perspective
