The IJtunnel, opened on 30 October 1968, is an automobile tunnel under the IJ that connects the centre of Amsterdam with Amsterdam-Noord.
The route through the IJtunnel is an urban avenue, formed out of two divided tunnels, each with two lanes of traffic.
This four-lane road continues to the A10 in the north and to the Prins Hendrikkade in the south, where it is reduced to two lanes, one in each direction.
[1] The tunnel is also an entry point to Amsterdam's low emission zone,[2] and there is a height limit of 4 meters.
However, the ban on pedestrians, bicycles and mopeds may be temporarily lifted if public transport and ferry services across the IJ are suspended: such a situation occurred in 1993, 1997, 2005 and 28 May 2019.
