The boundary between the cities of Manchester and Salford runs down the centre of the River Irwell.
Boatbuilding has been part of the life of the River Irwell from the earliest times, and the river has always been navigated for trade. In 1828 the biggest boat yet to be built on the Irwell was launched into the river; she was named the Emma, after the builder’s daughter. On the day, great crowds assembled on the banks of the Irwell, bands played and the Lord Mayors of Manchester and Salford attended the ceremony with a huge entourage. It was a carnival atmosphere with children playing and vendors clamouring for business.
When the ship was launched a huge cheer went up, but the triumphant moment soon turned to disaster. The boat powered across the river and smashed into the opposite bank, the dignitaries were thrown into the water, amongst them women and children and guests of the Lord Mayors of the two cities.
The Emma rolled over and capsized. Onlookers dashed down the banks to help but were soon adding to the terror of the moment. 22 people died that day, including

According to Noah Rose "In July 2006, after 5 years planning, the boundary between the neighbouring cities of Manchester and Salford was made visible with a 300m long pink dotted line, floating down the dead centre of the River Irwell. This temporary installation was conceived by Andy Farrell Readman and myself back in 2001. The installation turned out to be more temporary than we envisaged. On the day that the work was(Submitted on November 8, 2026, by Ian Lefkowitz of New York, New York.)to be launched - in front of an audience of visiting artists from Scotland - it turned out to have disappeared without a trace. The reason for its disappearance has not yet been satisfactorily explained. The pink polystyrene-and-steel floating boundary is missing, presumed on a round-the-world voyage. It may yet resurface in another location to divide or reunite two places which share some history"Photographed by Ian Lefkowitz, September 14, 20263.

2. Emma (1828 ship) (Wikipedia).
The Emma was a river flat launched on 29 February 1828 along the Mersey and Irwell Navigation, in Manchester. Built by the New Quay Company, it was one of the largest cargo vessels to be built alongside the Irwell. The vessel capsized shortly after its launch, causing the deaths of as many as 47 of its estimated 200 passengers.(Submitted on November 8, 2026, by Ian Lefkowitz of New York, New York.)
