The Aber Swing Bridge, also known as the Pont yr Aber and Caernarfon swing bridge, is a pedestrian swing bridge in Gwynedd, Wales.

[1][2] This footbridge crosses over the Afon Seiont from the foreshore to the Watergate entrance in the centre of Caernarfon near Caernarfon Castle.

It was built in 1970, is made of concrete and steel, and is powered with electricity.

That first bridge was built to replace the ferry.

For a short time after that, there was a bailey bridge.
