Hadera Power Station Long line into the sea

https://www.openstreetmap.org/#map=15/32.4665/34.8849

Can someone explain this line towards the sea?
Could it be a mistake?

It doesn’t look like a mistake according to the aerial imagery…

YaronS,

The map does not always show enough details. In order to know what’s in the OSM data, you can click on the “layers” button and activate the “Map Data” layer.

Clicking on the long blue line that now shows on the map, you can see it has a man_made=pier tag.

Thanks guys!
