Replacement of braking works Kooybrug (N99)

Rijkswaterstaat postponed major renovation work on the Kooy Bridge in October. In the intervening period, minor work will be started on the Kooybrug N99 near Den Helder. These works cause no or limited disruption to road and shipping traffic.

From Monday, November 27, 2023 to Friday, February 23, 2024, the waiting area facilities for shipping and braking works of the Kooy Bridge will be replaced. In addition, a number of small parts of the bridge will be replaced, such as handrails and access doors.

No or limited disruption to road and shipping traffic

During this period there will be limited disruption to shipping traffic with a clearance above 8.3m over the Noordhollandsch Kanaal. Operation of the bridge for these vessels is upon request and can be requested up to 24 hours in advance. Ships lower than 8.3m are not affected. We recommend waterway users to be well prepared when entering the water and to check the website in advance to consult. The work will cause limited inconvenience to road users from Monday December 11 to Wednesday December 13 due to a number of traffic stops (approximately 2 per day) lasting a maximum of 15 minutes at a time. Traffic stops will take place again in February 2024 and are currently being scheduled.

Previously, from Monday 20 to Friday 24 November 2023, the graffiti was removed from the bridge, an anti-graffiti coating was applied, concrete damage to the substructure of the bridge was repaired, the staircase was renovated and the access doors, fencing and a hatch were replaced.

Postponement of major renovation work

At the end of October, Rijkswaterstaat indicated that major renovation work on the Kooy Bridge had been postponed due to the coincidence of the renovation of the Kooy Bridge and ProRail's work on the track between Heerhugowaard and Den Helder. Rijkswaterstaat, together with VolkerWessels, is investigating when the major works can be rescheduled. This is done in consultation with the surrounding area due to the impact of the work on the accessibility and economy of the region.
