The tunnel was built by a consortium of Franki Construct, Heijmans, Royal BAM Group, Philipp Holzmann, TBI Beton- en Waterbouw Voormolen and Wayss & Freytag[1] on behalf of NV Westerscheldetunnel (Western Scheldt Tunnel Company), which is 100% owned by the province of Zeeland.

Since then, the two automobile ferry lines Flushing-Breskens and Kruiningen-Perkpolder, operated by the Provincial Steamboat Service (Provinciale Stoombootdiensten), have been discontinued.

The Western Scheldt Tunnel is 11.3 metres (37 ft) diameter, 6.6 kilometres (4.1 mi) long, with on the south end a 1,200 metres (3,900 ft) stretch of road with an uphill grade of 4.5%.

The tunnel reaches its deepest point under the Pas van Terneuzen shipping lane, 60 metres (200 ft) below water level.
