When will the new sea lock be completed?

The world’s largest sea lock at IJmuiden provides access to the Amsterdam port area. Construction works will be carried out at the lock complex for the duration of the construction period. The parties involved in the construction of the new sea lock will do everything possible to ensure that shipping traffic can pass smoothly and safely.

Why a new sea lock?

  • The North Lock will reach the end of its technical service life in 2029 and has become too small for today’s ever-larger seagoing vessels.
  • The New Sea Lock is tide-independent and can be used 24/7.
  • A new large sea lock allows new-generation larger vessels to pass through the North Sea Canal smoothly and safely.
  • With a larger lock, the port has the possibility to grow from today’s 90 million tons to 125 million tons of goods handled per year.
