The area still smells at times and maybe it is because I am not a local that I can get the smell well away from the river. But to be fair the river Liffey was much worse about twenty years ago [not sure why it has improved]

The Lagan Weir, in Belfast, crosses the River Lagan between the Queen Elizabeth Bridge and the M3 cross-harbour bridge. Prior to the building of the weir, the river would be subject to tidal fluctuations, and low tide would expose mudflats, which were unsightly and emitted a strong odour, particularly in the summer months. Opened in 1994, the weir was seen by the Laganside Corporation as a catalyst for its redevelopment projects and was judged to be the "centrepiece" of that effort. The weir also incorporates a footbridge.

A pedestrian bridge was constructed over the weir and connects Donegall Quay with Queen's Quay. The original bridge, which was narrow and required spiral access ramps at either end, was located above the weir gates and supported by the weir gatehouse structures. This was removed in 2014 to allow the construction a new structure, which provides access for both cyclists and pedestrians. The new bridge was erected by Graham Construction at a cost of £5m and is approximately 8 meters wide at its widest point. I like the new bridge.
