In 1770, Parliament passed legislation for improving the navigation of the River Clyde to the city of Glasgow. The act empowered the Magistrates and Town-Council to repair and enlarge the quay on the north side of the river, and build a new one on the south side. The legislation allowed the Glaswegian magistrates to levy a duty on river traffic, to which the Magistrates and Community of Dumbarton claimed exemption based on a 1770 contract between the two burgs.
