Hoevelaken interchange

Hoevelaken interchange has been in the Top 10 traffic jams for years. A radical innovation of the interchange and the expansion of the access motorways A1 and A28 should strongly improve the traffic flow here. This will happen in a complex administrative context with many surrounding parties, in an area that often has only limited space. The spatial quality also has to be improved in this process, and the interchange is to become an icon. CA1|28 works within a special contract: Plan-Design-Construct (PDC). In this, ARCADIS integrates its unique experience in both plan procedures, design and execution in one project. The project has landscape architects and architects working integrally on the design, in close consultation with builders, contractors and managers.

The plan entails an entirely new configuration of the interchange, in which the landscape has a leading role. The cloverleaves will be replaced with long link curves arranged around a ‘bowl’. The bowl itself is an open space, surrounded by a high edge with a circle of trees. It will improve the flow of traffic and create a unique landscape as a landmark for road users. In addition to the basic scope, CA1|28 also met all government and regional requirements, such as expanding the rest areas and new (slow) traffic connections. The project entails two all-new rest areas and expansions of two existing rest areas.
