 With the opening of the Broadwaters extension of the Wednesbury Canal, which served coal mines near Moxley, there was additional traffic through the junction and over the summit, and the building of the Birmingham and Fazeley Canal threatened to make the situation worse.The company therefore decided to make the summit lower in 1787, and this was achieved in two stages.The first was a new cut lower than the original summit, which eliminated two locks at either end, and was completed on 2 July 1789.
