AGENDA
Why ABC?
Pioneer Crossing Overview
ABC Falsework Types
Self Propelled Modular Transporters
Bridge Move
• Design Requirements
• Lift Supports
• Travel Path
• Geometry Control
• Public Involvement

WHY ABC?
Reduces Road User Costs and Impacts
Reduces Construction Schedule (Preferred by
Businesses and Commuters)
Improves Quality of Construction (Controlled
Environment)
Improves Safety of Traveling Public and Construction
Workers
