In 2021, the A27 interstate between Houten and the Hooipolder junction will be widened along a stretch of 47 km to improve future traffic flow. This means that a large part of the existing oil pressure connection underneath the A27 near Gorinchem has to be replaced. This connection runs through a densely populated area with lots of nature and existing water, gas and electricity infrastructure. With a traditional excavation, the work would damage the flora and fauna and cause a great deal of inconvenience to the residents. That is why a different approach and solution was needed.
