A nationwide transport strike in the Netherlands became an opportunity for the city’s cyclists, as a car-only tunnel was turned into a highway for bikes.

The 1.6km-long IJtunnel connects the centre of Amsterdam with the north of the city and is usually only open to motor vehicles.

But as Dutch workers went on strike across the nation and transport ground to a halt, officials opted to take the unique opportunity and open the tunnel to cyclists on Tuesday (May 28).

Most trains, buses, trams and ferries were stopped amid the industrial action, but Amsterdam cyclists were able to efficiently make their way around.

Video footage from the tunnel shows a huge number of people using the route, which runs under the IJ waterway.

The Dutch Cycling Embassy said on Twitter: “There is a major public transport strike today, which means no train, tram, bus, or ferry service across the Netherlands.

“To retain timely and efficient access to the city, Amsterdam opened the (previously car-only) IJtunnel to bikes and emergency services.”

Cycling is ingrained in the Dutch DNA after major investment in two-wheeled transport started in the 1970s.

A post-war boom in car use in Amsterdam led to 3,000 people being killed in 1971, 450 of them children, with money being spent to improve cyclist safety.

That investment has resulted in 400km of bike paths across the city, with around half of journeys being undertaken by bike.

Back in Britain, two thirds of people say that cycling is “too dangerous,” according to a National Travel Attitudes Study – exactly the same number as in 2011.

The government’s walking and cycling strategy states that it wants these currently underused modes of transport to be the ‘natural choice’ for shorter journeys by 2040, but progress is currently going in the wrong direction.

Multiple surveys have shown that close passes are one of the biggest deterrents from cycling, alongside sharing the road with lorries and poor road surface.

A recent British Cycling survey of its members showed that a similar number – 66 per cent – felt concerned for their safety whilst cycling on the road, and 79 per cent regarded close passes as one of the major hazards.
