Challenges
• Very heavy deck
• Bridge crossing crucial road open to traffic, implying totally safe operation
• Demanding work cycle
• Relevant inactive time between the 2 decks construction
• Turnkey solution required: machine + operation
• First Span built over existing road – limited time for operations during road closure
