Joint management of the Stadsbaantunnel Utrecht
The Stadsbaantunnel in Utrecht is owned by the municipality of Utrecht. It runs alongside the state tunnel of the A2 motorway which is owned by Rijkswaterstaat – the Dutch Ministry of Infrastructure and the Environment responsible for the design, construction, management and maintenance of the main infrastructure facilities in the Netherlands. Twynstra supported both the municipality of Utrecht and Rijkswaterstaat by looking into the options of working together for management and maintenance purposes.
