The Piet Heintunnel is open again. The tunnel is ready for the future. All technical installations have been replaced, the ceilings at the entrance to the tunnel have been given a heat-resistant layer, the escape doors have been renewed and the asphalt of the road has been replaced. The Piet Hein tunnel is also the first of the Amsterdam road tunnels to have new operation, monitoring and control, which has been extensively tested and for which air traffic controllers have been trained.
All these different activities had to be coordinated and were technically challenging. The fact that tram line 26 continued to run also made the renovation not easy. The work was also complicated and delayed by corona. The tunnel was closed from June 25, 2021. As a result of all these factors all together, the renovation took three months longer than planned. The last stretch has also been tough in recent months, especially for the people of Amsterdam, where the closure of the Piet Hein tunnel caused a nuisance. The tunnel now fully complies with the law again.
