World's longest purpose-built pedestrian tunnel?
Where is the world's longest publicly accessible purpose-built pedestrian tunnel?
Wikipedia has:
List of long tunnels by type, bicycle and pedestrian. This is incomplete, as the only long pedestrian tunnel I've been in, the 1.6 km Niwärch tunnel (photo), was unlisted until I added it. Worse, many of the entries are not pedestrian tunnels, but tunnels for disused railways now open to the public. That's cheating.- A category on pedestrian tunnels, which is even more incomplete (only 13 entries!).
Where is the longest purpose-built pedestrian tunnel in the world? By a pedestrian tunnel, I mean a tunnel that, when built, was not designed for anything larger than a pedestrian or possibly cyclists. For example, the Niwärch tunnel counts; built for water + human but has always been publicly accessible, but does not fit anything larger than a pedestrian (the watercourse is less than a metre wide). Disused railways that are now open to foot and bike traffic don't count. For the purpose of my question, it should be a simple tunnel connecting A to B; large networks of underground pathways such as the Toronto PATH do not count, for the same reason that the Shanghai Metro does not count as the world's longest railway tunnel.

@gerrit you might like to know tripadvisor.pt/… Probably not on list of longest, since it's only 500mts but very, very intersting pedestrian tunnel. It's in antwerp and goes under the river. It's accessible through wooden automatic stairs. Very nice.

@gerrit I agree with you about Standedge, but perhaps more interesting is that, lacking a towpath like most other canal tunnels, it was designed for the source of motive power to be human legs - so nearly pedestrian, and yet so definitely not!

Are you including those built in city subway systems? Toronto's PATH underground passenger system is about 30 km long, although it also added elevated and at grade walkways.

Perhaps not what you're after, and maybe doesn't qualify due to being a 'network', but the 121-km long Củ Chi tunnel network is worth noting. Since the criteria is continuous length, you'd have to work out what the longest continuous stretch in there is.

Your conditions are quite strict - "Longest", "publicly accessible", AND "purpose-built". A "simple tunnel connecting A to B".
There is indeed a tunnel that meets these criteria that at 1,635 metres is slightly longer than the one you've mentioned. The tunnel itself IS publicly accessible, although at the current time it's entire length is not accessible - only part of it.
For this "simple tunnel", point A is North Korea. Point B is South Korea. And the tunnel is commonly known as the 'Third Infiltration Tunnel'. It was built to allow "pedestrians" (in the form of North Korean soldiers) to travel from North Korea into South Korea. The southern end of the tunnel is currently open to the public (with restrictions around nationalities that can visit, but still...) and you can travel some way into the tunnel below the DMZ between the two countries.
Two additional, much longer tunnels in the same area meet all of your criteria except for not being publicly accessible. The first and second Infiltration Tunnels are both around 3.5km long and were purpose-built for "pedestrians". The forth Infiltration Tunnel rounds out the set, but is only around 2km long.

@gerrit I agree with you about Standedge, but perhaps more interesting is that, lacking a towpath like most other canal tunnels, it was designed for the source of motive power to be human legs - so nearly pedestrian, and yet so definitely not!

Are you including those built in city subway systems? Toronto's PATH underground passenger system is about 30 km long, although it also added elevated and at grade walkways.

Perhaps not what you're after, and maybe doesn't qualify due to being a 'network', but the 121-km long Củ Chi tunnel network is worth noting. Since the criteria is continuous length, you'd have to work out what the longest continuous stretch in there is.
