Glasgow-Edinburgh Motorway 30. Mr. Rankin asked the Secretary of State for Scotland for how long the motorway between Glasgow and Edinburgh has been under construction; and when it will be completed. Mr. Younger Construction of the motorway section of the Glasgow to Edinburgh trunk road began in September, 1963, and my right hon. Friend will be opening the final length of it at the end of this month. Mr. Rankin At least that is one cheery little note from the Front Bench opposite. But will the M6, which is proceeding so smoothly and efficiently on the English side of the border, soon show signs of existence on the Scottish side? Mr. Younger The question of the M6 is entirely different from that of the M8, but I can tell the hon. Gentleman that work is proceeding on joining up the M6 and the M74, and we see no reason why it should slowing down.
