It ends at Amsterdam in the closed-off [[IJ (bay)|IJ Bay]], which in turn connects to the [[Amsterdam-Rhine Canal]]. The drainage of the canal to the North Sea is done through the Spui [[Lock (water transport)|Locks]] at IJmuiden, augmented by the largest pumping station of Europe. This system is vital to the ground water management of western Netherlands. == History == To improve the connection between the harbour of Amsterdam and the North Sea, the [[North Holland Canal]] was built in 1824. But this long and narrow canal was quickly inadequate to handle the growing boat traffic. A few decades later it was decided to dig a new canal at the narrowest point in Holland and thereby providing the shortest route to the sea. Digging began on March 8, 1865, at the dunes of [[Breesaap]] and lasted until 1876. Since no Dutch company was willing to take on this task, the project was awarded to an English contractor. The North Sea Canal was built by digging a channel through the old IJ Bay and lining it with dikes, after which the remaining portions of the IJ Bay were reclaimed and turned into polders. From this bay to the sea, a new canal was dug through the dunes at [[Velsen]]. To accommodate drainage of and shipping on the tributaries of the IJ, such as the [[Spaarne]], the [[Zaan]], and the [[Nauerna Canal]], 9 auxiliary canals needed to be dug as well (Side Canals "A" to "I"). A small set of locks ("''Zuidersluis''") were built at the mouth in 1876 where the new town of [[IJmuiden]] (Dutch for "IJ Mouth") formed. In 1896 the Middle Locks ("''Middensluis''") were built, followed by the North Locks ("''Noordersluis''") in 1929, which were Europe's largest locks at that time. [[Image:Velsen.gif|thumb|left|200px|Historic map of Velsen showing the western portion of the IJ and the planned route of the canal.]] At the eastern end of the canal, east of Amsterdam, the IJ Bay was open to the [[Zuiderzee]] until 1872 when the Orange Locks ("''Oranjesluizen''") were built. With the completion of these locks the North Sea Canal and IJ Bay were no longer open to the sea and a specific water level could be maintained. The canal was dug using manual labour. The workers lived in horrid conditions, being housed in huts built from twigs, driftwood, sod, and straw, where disease, fights, and alcohol abuse were rampant. <ref>Connie Braam, ''De Woede van Abraham'', 2000, Amsterdam, ISBN 978 90 45702 223</ref> On November 1, 1876, the North Sea Canal was officially opened by King [[William III of the Netherlands]]. Over the years the canal has been widened and deepened several times. == Side canals == The North Sea Canal and the IJ have 10 side canals (in Dutch: ''Zijkanaal''), which connect to rivers and other canals which used to flow into the former IJ Bay before its reclamation. * ''Zijkanaal A'' - connects the harbour of [[Beverwijk]] to the North Sea Canal, also an inundation canal of the [[Stelling van Amsterdam]]. * ''Zijkanaal B'' - connected [[Spaarndam]] to the North Sea Canal, but was cut off from it by the construction of the [[A9 motorway (Netherlands)|A9 motorway]] in the 1960s. It is now used for canoeing and [[Mooring (watercraft)|mooring]] of [[houseboat]]s. * ''Zijkanaal C'' - connects the [[Spaarne]] river at [[Spaarndam]] to the North Sea Canal at [[Buitenhuizen]], and also functions as the main drainage canal of the Rijnland [[Water board (The Netherlands)|water board]]. The A9 motorway has an operable bridge over this side canal. * ''Zijkanaal D'' - connects the [[Nauerna Canal]] to the North Sea Canal. * ''Zijkanaal E'' - a very short canal connecting the south end of [[Westzaan]] to the North Sea Canal. * ''Zijkanaal F'' - connected [[Halfweg]] to the North Sea Canal, but is now mostly backfilled. A small portion remains and is used as a drainage canal. * ''Zijkanaal G'' - connects [[Zaandam]] and the [[Zaan]] River to the North Sea Canal. * ''Zijkanaal H'' - connects the [[Barndegat]] to the North Sea Canal. * ''Zijkanaal I'' - connects the East Zaan Overtoom to the IJ Bay. * ''Zijkanaal K'' - connects the harbour of [[Nieuwendam]] to the IJ Bay. ==Locks== [[Image:IJmuiden sluis Noordzeekanaal 20050928 40421.JPG|thumb|230px|right|Mouth and locks at the North Sea.]] There are four locks, of various sizes at the North Sea mouth of the canal: <ref>Letter, from an official, in response to a query on the lock dimensions.</ref> {| class="wikitable" style="text-align:center" |- ! name !! completed !! dimensions (L x W x D)<br>meters !! dimensions (L x W x D)<br>feet |- | South || 1876 || 110 x 20 x 8 || 360 x 65 x 26 |- | Small || 1876 || 110 x 11 x 3.5 || 360 x 36 x 11 |- | Middle || 1896 || 225 x 25 x 10 || 738 x 82 x 33 |- | North || 1929 || 400 x 50 x 15 || 1312 x 164 x 49 |} ==Crossings== [[Image:Noordzeekanaal_4.78260E_52.41452N.jpg|thumb|right|230px|Satellite photo]] Railway [[tunnels]] (with nearest train station on the south and north bank): *between [[Amsterdam]] Sloterdijk and [[Zaandam]] *between [[Velsen|Driehuis]] and [[Beverwijk]] Road tunnels, from east to west: *Zeeburger Tunnel and Zeeburger Bridge *Zuiderzeeweg *IJ Tunnel *Coen Tunnel *Wijker Tunnel (part of the [[A9 motorway (Netherlands)|A9 motorway]]) *Velser Tunnel Several [[ferries]].
