That the Parliament celebrates the 50th anniversary of the opening of the Clyde Tunnel in Glasgow, which took place on 3 July 1963; notes that the tunnel links Whiteinch and Govan in Glasgow and now carries, on average, 65,000 vehicles per day; looks forward to an open day of celebrations on 7 July; considers the tunnel to be one of the best and most consistent transport links in the west of Scotland for the last 50 years, and recalls that when the tunnel was built, it not only had the steepest gradient of any tunnel in the world but was supposed to carry only 13,000 vehicles per day.
