Development of the Glasgow motorway system can be traced back to the mid-1940s. In the eighty or so years since there have been numerous milestones, with the construction of routes such as the M8, M74, Erskine Bridge and Clyde Tunnel.
To provide a summary of these key dates, we have created this timeline page. Its aim: to provide a quick reference point for those looking for scheme dates or information on specific events. Links to relevant pages are highlighted bold where present, and photos and other media are also included.
