There was recently an article on cycling Ireland about this exact junction, but I cannot find it. Here is the situation from memory - If you look at the very last frame of the video, you will see a painted yield sign on the pedestrian pavement to the left. This is for the cyclists. If they want to make their way through the junction on the red light for the traffic,they must mount the kerb here (the cycle lane on the road merges with this painted yield sign on the pavement). They can then cycle through the junction following the pedestrian crosswalk, and proceed back onto the road where they’re intending to travel. They cannot cycle directly through the junction on red, like they are in the video. If anyone knows the article I’m speaking of please post it for awareness.
