Here's a description of the video: The video shows a nighttime view from the pedestrian walkway of the Tower Bridge in London. The perspective looks toward one of the bridge's towers. The tower is illuminated and the sky is dark. Cars are moving through the bridge's roadway. The walkway appears wet, likely from rain. In the background, lights from other buildings are visible, and "The Shard" skyscraper can be seen in the distance. Pedestrians can also be seen in the video.
