The Moerdijk bridges in the Netherlands are bridges that connect the Island of Dordrecht with the Dutch province of North Brabant (Noord Brabant) across the Hollands Diep. The first bridge was built at the end of the 19th century, and was a railway bridge. The second bridge was built in the 1930s for road traffic, and is currently part of the A16 motorway. This bridge was replaced in 1978 by a more modern, wider bridge. A second railroad bridge was finished in 2006, as part of the HSL-Zuid project.
The HSL bridge is located a few dozen meters west of the existing railway bridge and also has ten spans. The pillars stand in the flow direction of view of the river, in line with those of the existing railway bridge, so there are no additional obstacles to shipping arise. The HSL-bridge has a distinctive shape, which is made up of Y-shaped bearings which pass almost seamlessly in the steel , tubular spans. In October 2004, with dozens of truckloads of sand tested whether the bridge would bend a few centimeters would in fact already be disastrous for the fast train. Eventually, the bridge turned out to only 12 mm down.
The first high-speed train , the new bridge passed in 2006 during a test drive of about 300 kilometers per hour.
In the beginning of Battle of Holland, 10 May 1940, bridges were captured during paratroopers operation and held 4 days, until German forward forces arrived. In 1944, both the road and railway bridge were destroyed by the Germans, to prevent the Allied Forces from reaching South Holland.
