Qorro's Bridge

Qorro's Bridge, also called the New Bridge, is one of the two viaducts spanning the River Helvander to connect the High City and Low City districts of Torrune (the other is the Fortress Bridge or Dwarven Bridge a short distance downstream). The third bridge to cross the Helvander at Torrune, the Nyrrian Bridge running from the Low City to Fenside, is another half-mile upstream. 
Unlike the ancient Fortress Bridge, Qorro's Bridge is of relatively recent construction, dating only back to the early years of the Helvandrian League. It was completed in 1050 CV and is named for the chief mason and architect who oversaw the project, Qorro of Temsevar. It was built to alleviate chronic and worsening congestion on the overcrowded Fortress Bridge, which was, up until then, the only way to cross between the High and Low Cities without getting on a boat. As Torrune grew ever bigger and more prosperous in the boom time of the early League years, the Fortress Bridge alone was no longer sufficient for the daily horde of wagon and foot traffic moving back and forth across the river. 
Although an impressive feat of engineering, Qorro's Bridge is not as architecturally sophisticated as the dwarf-built Fortress Bridge. Its arches are lower, narrower, and more numerous, limiting the size of boats that can pass between them. The flow of water between the arch piers can sometimes be dangerously quick, especially when the river is high and thus running swiftly; when the Helvander is in flood, the gaps between the piers practically resemble whitewater rapids, and only the most daring boatmen will attempt to pass under the bridge.
The south end of Qorro's Bridge meets the High City's riverfront wall at the XXXXXX Gate, and its north end comes ashore in the Low City at the tip of XXXXX Point, just west of the [Floating Village].
