Further to the south is the city’s widest (97 metres/300 ft) Blue Bridge, often called ‘square bridge’, across the Moika River. On the left side of the bridge a water-measuring post is cut into the Moika Embankment and crowned with Neptune’s trident. The post has signs marking the levels of the Neva in the days of the big city floods.
