A29: closures Heinenoord Tunnel


The renovation of the Heinenoord Tunnel on the A29 highway started in 2023. Renovations will continue until the end of 2024. This will result in various overnight and weekend tunnel closures, usually in one direction. The tunnel will be closed in both directions during the summer. Traffic will be diverted and road users should expect longer journey times.
More information on the renovations, closure schedule and diversion routes is available on this website.







Why renovations?

To ensure that people and goods reach their destinations quickly and safely, Rijkswaterstaat is working on safety, accessibility and liveability. On the road and on the water.  

Rijkswaterstaat is renovating the Heinenoord Tunnel on the A29 highway in 2023 and 2024. The Heinenoord Tunnel is the first of eight tunnels to be renovated in Zuid-Holland. The tunnel was taken into operation in 1969 and is due for a major upgrade. For instance, the tunnel’s technical installations are at the end of their technical lifespan and are in need of replacement. 

Various works were carried out in 2023, including modifications to the power supply and service buildings, asbestos remediation, replacement of the rainwater discharge system, concrete repairs, work on the lighting grilles and construction of a central gallery. This is an enclosed escape tunnel in the centre of the tunnel.  The renovations will continue until the end of 2024.

The tunnel will be closed at various times to ensure safety during the renovations. Allow for additional journey time on top of the usual journey time.





Advice to road users 

Rijkswaterstaat will minimise the disruptions. As well as diversions and communications, this includes such measures as adjusting traffic lights to improve traffic flow and campaigns to stimulate cycling and the use of public transport. 

You can also take action yourself to minimise disruption: 

  • ​be well prepared before departing;
  • be aware of when roads or waterways are closed and what the diversions are;
  • check current traffic jams and diversions before you leave via existing apps, rwsverkeersinfo.nl or van AnaarBeter.nl.

And once you are at your destination, please consider:

  • renting an e-bike/bicycle for short distance travel;
  • travelling by public transport. You can buy a Tourist Day Ticket, with which you can visit the whole of South Holland as you wish: touristdaytickets.com;
  • travelling at other times (outside peak hours);
  • avoiding the diversion routes.


Cyclists and pedestrians

There will be no inconvenience for cyclists and pedestrians at the Heinenoord­Tunnel. They can use the Second Heinenoord Tunnel as they do now. For cyclists and pedestrians, the crossing via the ferries at Rhoons veer, Puttershoek and Nieuw-Beijerland will be free of charge during closures of the Heinenoord Tunnel.
