As part of the bridge improvements, overseen by the architect Sir Robert Taylor, a new pedestrian walkway was built along the eastern side of the bridge. With the other buildings gone St Magnus blocked the new walkway. As a consequence it was necessary in 1762 to 1763 to remove the vestry rooms at the West end of the church and open up the side arches of the tower so that people could pass underneath the tower. The tower’s lower storey thus became an external porch and two windows were lost from the north facade. Internally a lobby was created at the West end under the organ gallery and a screen with fine octagonal glazing inserted. A new Vestry was built to the south of the church. The Act also provided that the land taken from the church for the widening was "to be considered ... as part of the cemetery of the said church ... but if the pavement thereof be broken up on account of the burying of any persons, the same shall be ... made good ... by the churchwardens".
