Why are there so few bridges across Amsterdam’s largest river?

The IJ River cuts right through Amsterdam. Sure, it has tunnels, but where are all the bridges?

What is Amsterdam famous for? Besides being Europe’s Sin City, and having one million bicycles, it’s also known as ‘Venice of the North‘. The city has more than 100km of canals and more than 1,200 bridges.

The IJ River divides the north and south of Amsterdam. The IJ is a pretty odd river. For one thing, its name is a single letter in Dutch, which is why IJ is fully capitalised. (To be more precise, IJ is a digraph that behaves like a single letter).

The IJ is also not a real river. It’s a former bay that changed in shape, thanks to the Dutch national hobby of reclaiming land. Technically, it’s a long lake, which connects a canal to another lake, which itself was formerly a sea.

But let’s not make things too complicated: the Dutch say the IJ is a river, and so will we.

None of that, though is what’s odd about that picture. For a city known for its bridges, very few span its major river. In fact, there’s just one bridge, the Schellingwouderbrug, (The Zeeburgerbrug and Enneüs Heerma come close but don’t actually cross the IJ). However, funding has been set aside for new bridge construction, according to the NL Times, as Amsterdam-North-based entrepreneurs continue to campaign for access across the river.

Amsterdammers can only ride their bicycles from the city centre to the northern part of the city by using a network of free ferries. These are very cute and quite convenient: the ferry right behind Amsterdam Central Station leaves every six minutes and takes about five minutes to cross the river.

But a ferry is no bridge, and cycling across the same stretch of river would only take about 45 seconds (and burn a little over eight calories).

So why has no bridge ever been constructed across Amsterdam’s IJ?

We asked Bas Kok, the author of Oerknal aan Het IJ (Big Bang on the IJ), a book about the history of Amsterdam-North. He says that there is no technical reason why a bridge couldn’t be constructed. The span of the IJ is between 200m and 300m, similar to the Thames. But for a long time, there was simply not enough demand.

“Between about 1300 and 1795 the north bank of the IJ was a field of gallows. In the 1800s and 1900s, the area was transformed into an industrial estate. It wasn’t a very nice area: you wouldn’t go there unless you absolutely had to. The North was the ugly duckling of the city, so why would you build a bridge there?” Kok explained.

That’s not to say the idea hasn’t been raised before, he added. But the maritime lobby managed to deter these plans, on the grounds that obstacles in the river would harm trade.

“In the 20th century, people in Amsterdam looked down on the inhabitants of Amsterdam-North. They were working-class people, who didn’t have much business in the city centre. It was decided that they wouldn’t need the convenient connection a bridge would offer.”

But now, the north bank is booming. After a Shell research facility just across the river from the Central Station moved to another area in the borough, the development of a new neighbourhood started in 2007. A beautiful new film museum opened in 2012, a cultural centre and concert venue opened in 2014 and a new dance music hub was developed in a 100m-high tower.

Across the rest of the northern borough, houses and entire new neighbourhoods are being constructed. The borough’s population is expected to have risen by 30–50% ver the past decade. 

Those free ferries are having a hard time coping with the increased use. Recently, demand has risen and during rush hour the traffic on the ferries is busy. However, the NL Times reports further ferries will set sail in the coming years.

Traversing the river is no easy task: the Amsterdam harbour still draws a lot of traffic, and a large cruise terminal on the south bank opened in 2000, which means any bridge would need to be able to let cruise ships pass. One idea was a set of two bridges across the river, on either side of the city centre.

In the meantime, however, architects are having a field day coming up with what these bridges might look like. Several more and less serious proposals for colossal bridges are popping up.

In a few years’ time, when Amsterdammers are cycling across the IJ, hopefully, they’ll be doing it in style.
