The Belgian Tunnel Association (ABTUS-BVOTS) will organise the event, to be held in Antwerp from April 23-29, 2027.

“We are extremely excited about the decision to choose Belgium,” said Johan Mignon and Bart De Pauw on behalf of ABTUS-BVOTS. “In 2027, the Oosterweel project, with its various tunnel complexes, will be in full swing, which has certainly been an asset in our candidacy. But there are also numerous examples elsewhere in our country of underground infrastructure that has enabled our region to develop into a prosperous and thriving area over the past decades”

ITA president Arnold Dix said he was looking forward to participating in the congress in Antwerp.

“Belgium’s underground infrastructure is characterised by a blend of historical heritage, modern technology, innovative engineering, and cultural significance. I am confident that this event will make a valuable contribution to furthering underground construction worldwide,” said Dix.

ABTUS-BVOTS is now seeking sponsors for the 2027 event. For more information, contact
