Project Overview

In Spring and Summer 2023, Advanced American Construction (AAC) assembled and installed a 208’ long deck plate girder bridge for BNSF Railway near Stevenson, WA. Lampson International provided expert heavy lift support for the critical bridge changeout, utilizing two Manitowoc 4100 Ringer Cranes.

Project Highlights

  • Crane Used: Two Lampson Manitowoc 4100 Ringer Cranes
  • Girder Specs: 208’ long, 12’ tall, ~310,000 lbs each
  • Existing Bridge: 150’ long, ~420,000 lbs
  • Rigging & Operations: Two-crane pick with full 360° swing
  • Stability Support: Cranes erected on Lampson steel “mud boats” for small pad footprint (50’x55’)
  • Permit Constraints: Tight site conditions due to limited fill in Rock Creek

Scope of Work

  • Assembly and lifting of four bridge girder sections
  • Removal of the existing 100+ year old railroad bridge
  • Demo of pre-cut concrete pier sections (~150,000 lbs each)
  • Precision placement and slide of the new bridge to allow crane counterweight clearance
  • Coordination under a 31-hour BNSF rail shutdown
  • Full adherence to safety and permit requirements
