The renovation of the Waal Bridge near Nijmegen is 25 million euros higher because the carcinogenic substance chromium-6 was found on a large scale during the activities, Minister Cora van Nieuwenhuizen of Infrastructure wrote in a letter to the House of Representatives on Monday.
The renovation of the arch construction of the bridge is being postponed for the time being due to the higher costs. That construction should be safe for another ten years. According to Van Nieuwenhuizen, there will be a budget in 2030 to tackle the arch construction.
The total cost of the revamp is now estimated at 65.2 million euros. Earlier, the costs were estimated at 40 million.
The renovation of the Waal Bridge, an important north-south connection for through traffic, started in March of last year. Originally, work was supposed to begin in June 2018, but the project was postponed because the bridge was full of paint containing chromium-6.
The carcinogenic substance was found in the preservation layer of the steel structure. The paint first had to be removed. Additional measures had to be taken to carry out the work safely and other permits, exemptions and safety plans were required.
It is planned that the road surface of the Waal Bridge will be released in mid-August.
