On this page, we are trying to keep you informed of any news from in and around the harbor!
If you know of something that should be on here and isn’t, feel free to let us know by sending an email to info@marina-numansdorp.nl and we will take it into consideration.

Haringvliet bridge
As most of you probably know, major maintenance is taking place this year on both the Haringvliet bridge and the Heinenoord tunnel (see more information about this in the next section). The bridge will open sparingly and for a period this year, it won’t open at all. This is due to the full replacement and maintenance of a major part of the Bridge.
Despite the fact that isn’t favorable for our current sailing season, this maintenance is badly needed and it does mean that after this we will have a well-operating and regularly opening Haringvliet bridge for many seasons to come.
Through the link below you can find detailed information about the bridge maintenance as well as the work planning calendar for the A29 (which crosses both the bridge and the tunnel):
A summary of this is:
- From 1 January 2023 until Autumn 2023 the Haringvliet bridge will not operate for tall ships (> 13 meter)
- From 9 June 22:00 – 28 July 2023 the Haringvliet Bridge is closed to all road traffic (motorway and parallel lane). An extension up to and including August 4 possible.
- During summer and autumn 2023, there will be approximately 10-night closures of the Haringvliet bridge for testing of technical installations.
Further information can be obtained from:
- the Regional Traffic Center Dordrecht by VHF-71 or VHF radio (0800) 023 62 00 or;
- the bridge keeper of the Haringvliet bridge via VHF-20 or (0186) 65 14 75 or;
- the lockkeepers of the Volkerak locks via VHF-20 or (0168) 47 75 00 or;
- www.vaarweginformatie.nl
The Haringvliet Bridge will not be operated above wind force 7 Beaufort, regardless of the wind direction.

Heinenoord tunnel Renovations 2023/20234
Unfortunately, both the Haringvliet bridge and the Heinenoord tunnel are in urgent need of major maintenance and the work will overlap this year. This means that in certain periods it takes some extra planning and travel time to get to Numansdorp. The website below clearly indicates per month which days and in which direction the tunnel is closed.
Alternative ways to reach the Hoeksche Waard are the Kilt tunnel and the Veerpond from Hekelingen to Nieuw-Beijerland (https://www.thequeenjacqueline.nl/).
