Tower Bridge at Night

Tower Bridge stretches across the Thames after dark, with its pale stone towers lit against a deep blue sky. Blue suspension lines sweep out from the towers, while warm lamps pick out the windows, walkways and lower span. Reflections break across the water below, so the river has movement instead of becoming a flat dark band.

Start with the two towers, especially the roof peaks, bright windows and arched openings near the bridge deck. The blue steelwork gives the middle of the puzzle a clear direction, and the white light strips are easy anchors along the spans. Save the river for later. Ripples and small gold reflections will sort better once the bridge shape is already in place.
