Introduction
Het Nieuwe Diep and Het Nieuwe Werk are two roads in the port area of Den Helder, located between the naval port and the city. The Moorman Bridge connects the area to the naval port, while the Van Kinsbergen Bridge provides the connection to the city. The roads and bridges in the area are important for sea-related activities, such as shipping, shipbuilding, offshore (energy), naval, and maritime services.
The area also includes the Havendijk, a primary sea defense that protects the area from high water from the Wadden Sea.
Part of the project involves improving the accessibility and quality of life in Den Helder. The intention is to separate urban traffic from through traffic to improve accessibility and flow through the port area. To this end, the province is working on a new bridge: the Ravelijnbrug. Under the leadership of the municipality of Den Helder, the project team is working on a connecting (re)design of the road from Nieuwe Diep/Nieuwe Werk. With this project, we are improving the traffic infrastructure and contributing to strengthening the economic and socio-structural structure of the region.
The goal is to realize the connection of the Ravelijnbrug and the Moorman Bridge to the Nieuwe Diep/Nieuwe Werk, in order to create a well-functioning road. This road should make it possible to better separate traffic flows and improve the accessibility of both the civil and military ports, in such a way that the activity at the civil port also benefits.
The Nieuwe Diep/Nieuwe Werk will – upon realization of both bridges – become a new ‘artery’. This calls for a coherent approach in cooperation with all parties involved. The new road must take into account pedestrians, cyclists, and motorized (truck) traffic, so that everyone can use it safely and efficiently.
Insight into what it yields
The development of the Nieuwe Diep – Nieuwe Werk (NDNW) area is an important step for the future of Den Helder. This area connects the port, the city, and the region, and is being designed to stimulate economic growth and cooperation.
For Den Helder, this means a stronger and more attractive city. The area will have better access with new waterfront connections and infrastructure, allowing residents and businesses to reach their destinations faster and more safely. Local entrepreneurs will have opportunities in the implementation and benefit from the improved accessibility and appearance of the area.
For the region, this means a strengthening of the maritime cluster in North Holland North. The area creates space for cooperation between Defense, civil companies, and educational institutions. Innovations are being developed here, for example in the field of sustainable shipping and energy. This creates new jobs and more training opportunities.

Studies
Mobility study Den Helder - Phase 2
The aim of the mobility study is to develop a set of mobility measures that contribute to better and sustainable accessibility, in order to create a realistic and feasible implementation plan for the Maritime Cluster.
The aim of this second phase is to gain insight into the developments, the traffic bottlenecks and which measures contribute to a good flow. The research consists of inventorying traffic flows, mobility data and analysis and explanation of challenges and measures.
Frequently asked questions
Here you will find answers to frequently asked questions that we regularly receive.
The Nieuwe Diep and Nieuwe Werk are important roads between the naval port and the city of Den Helder. The idea is that they – together with a new Ravelijnbrug bridge – will form a new traffic artery. The redevelopment will make the roads safer and more suitable for cars, freight traffic, cyclists and pedestrians.
The new design improves the accessibility of the port and the city, ensures a better flow of traffic and increases the quality of life. The civil port and local companies also benefit from the improved infrastructure.
The redevelopment is a collaboration between the municipality of Den Helder, the province of Noord-Holland, the Ministry of Defence and Port of Den Helder. The Hollands Noorderkwartier district water board is also involved. Together, they ensure a coherent development of infrastructure and the area.
There is a preliminary schedule: preparations will run from 2026 to 2027. In 2026, the environmental impact assessment (EIA) and the development framework will be established, among other things. In 2027, the decision-making on the
environmental plan will follow. The execution is scheduled for the period 2028–2032.
The municipality and project partners are organising information evenings and participation sessions, such as the meeting on the draft design on 15 October 2025. In addition, there is an advisory group that provides solicited and unsolicited advice to the project leaders and administrators. Residents and companies can respond to plans via opinions and consultation moments.
In the first half of 2026, we will organise another meeting for local residents and companies in the Nieuwe Diep/Nieuwe Werk area.
