Over the past month, the eight elements for the immersed tunnel have been towed over a 111km journey via the North Sea from Zeebrugge to the Scheldt river.

The tunnel sections, which were built in a specially built construction dock in Zeebrugge, measure 160m in length, 42m in width and 10m in height, and weigh approximately 60,000 tonnes.

The 1.8km-long Scheldt Tunnel is part of the Oosterweel Link, a ring road around Antwerp designed to improve links to the city and its port.

The tunnel is being delivered by the TM Cotu consortium comprising Besix, Stadsbader Contractors, Deme, and Jan De Nul.

Sightseers watched the elements at points on their sea journey, and TM Cotu and client Lantis are expecting today’s event also to attract interest.

The submersion of the first tunnel segment can be followed online here.
