Boskalis Nederland
Contract route
N206 Europaweg design-and-construct package: provincial intention-to-award decision in December 2023, design-team definitive-award announcement in February 2024. No separately priced bridge marine award identified.
Execution window
Contractor August 2026 bulletin announces September-October foundation/bank sequence and a later September cable-crossing window; these are planned dates, not accepted work or a commissioning deadline.
Works package
Replacement movable bridge basement, in-water central support foundations, navigation protection, bank sheet piles and underwater power/data crossing. Other N206 bridges and road elements remain distinct.
Marine interfaces
Weekday passage restrictions and a separate continuous cable-crossing closure interact with in-water workfront access. Longer possible working hours do not themselves alter navigation closure hours. The schematic is not a navigation notice.
Commercial evidence boundary
The operating connection and foundations require different access interfaces within a wider transport package. A contractor programme does not establish a new marine contract, subcontract allocation, selected vessel fleet or completed installation.
