Over the years, many ships have sunk in the Western Scheldt. Following an agreement between the Dutch and Belgian governments in 1995, many of the wrecks have been removed to improve shipping access to Antwerp. It was expected that the last 38 wrecks in the shipping channel would be removed during 2003. The largest wreck was the 131-metre (430 ft) long Alan A. Dale which was removed in June 2003.
In mid-March 2003, a 6.6 kilometres (4.1 mi) tunnel under the Western Scheldt opened, the Western Scheldt Tunnel, running from Ellewoutsdijk (mun. Borsele) in Zuid-Beveland to Terneuzen in Zeelandic Flanders. It is the longest road traffic tunnel in the Netherlands. The toll (2012) is €5,00 for cars and €2,50 for motorcycles. Prior to 2011, the charge for motorcycles was the same as for cars but it was reduced following protests. There is a single toll station for both directions, located on the north bank. Pedestrians, cyclists, and moped riders are not allowed in the tunnel and must travel by bus.
The double-decker car ferries that serviced the two Western Scheldt crossings until 2003 were sold to Italian companies, where two of them, the Queen Beatrix (renamed Tremestieri) and Prince Johan Friso (renamed Acciarello) were adapted for the crossing between Messina and Villa San Giovanni on the Italian mainland.
With the opening of the road tunnel, the Breskens-Vlissingen ferry was restricted to pedestrians and cyclists. It is operated by Westerschelde Ferry BV, a subsidiary of the province of Zeeland. The service initially used former car ferries, but as of 2 May 2004 it employs two "small waterplane area twinhulls" (swaths, similar to catamarans), built at the Royal Schelde Group in Vlissingen (Flushing), and named "Prins Willem Alexander" and "Prinses Máxima".
