The Caernarfon Swing Bridge is found crossing the River Seiont adjacent Caernarfon Castle. The town of Caernarfon is a beautiful clean Royal Town in the summer sun, sitting on the northwest coast of Wales just south of Anglesey. Unfortunately tidal rivers rarely look nice especially when the low tide exposes the mud. If you look carefully at the River Seiont on the left you will at least see through the water to the muddy bottom. This is the view looking up river from the mouth by Caernarfon Castle.
This must be the Stig of bus drivers getting his bus up this steep hill in one go without sliding all over the place in these snowy winter conditions.
This is miraculous driving of the X4 service single deck bus shown here going up Saltburn Road1 between Vista Mar and the Spa Hotel at Saltburn-by-the-Sea in North Yorkshire.
It must take a bit of skill in the summer never mind in these icy winter conditions. The road has a gradient of 25%.
The video shows several cars on the road many of which are having difficulty driving under these conditions. Some are skidding and others are being pushed, but this bus zips through them and drives straight up the incline without skidding or stopping.
For those who want to visit here is a travel guide to Saltburn-by-the-sea.
I have done my geography and looked at Google Maps to check the location of this steep winding road. I found the action happens on Saltburn Road and not Saltburn Bank as mentioned in the Simjem video. That is another road adjoining Saltburn Road to the east of this location.
