of the A74(M) at the Scottish border. It existed as an isolated stub from 1992, when the A74 was improved to motorway standard around Gretna, to 2008, when the M6 was extended northwards. Scottish ministers had previously expressed disappointment at slow progress over the border; in 1964, Dumfries MP Hector Monro stated "there is widespread feeling in the south of Scotland that the advance south over the Border of this important new road is being delayed because England is dragging her feet." When the M6 was complete around Carlisle in 1971, a new section of dual carriageway A74 was created to tie in with the original road running from Kingstown. The 1916 Metal Bridge also had to be replaced, in order to accommodate the increased traffic levels. An offer from the Scottish Executive to build the road to meet the M6 was not accepted by the English Highways Agency. This left a remnant of the old A74 as a stretch of two-lane dual carriageway between two long, three-lane motorways. Lex Gold, the director of the Scottish Confederation of British Industry, said "We are very disappointed indeed by this part of the programme revision. This will mean that for now and many years, road users will face a six-mile [9.6 km] dual carriageway between an excellent Scottish motorway and before the road widens for the existing M6." On 1 July 1999, following devolution, control of the A74 improvements passed over to the Scottish Parliament, meaning that they could only improve the route as far as the border. After years of political battles between the English Highways Agency and the Scottish Executive, followed by a lengthy design and public enquiry phase, the "M6 Motorway Extension Carlisle to Guards Mill" became part of the government's targeted plan of improvements in 2002, with the intention to start work around 2005–06 at a cost of £65 million. Due to delays with the G8 Conference in 2005, construction work started on 25 July 2006, and included a replacement for the 1971 Metal Bridge, and a new VOSA testing site. The new stretch of road was officially opened by Lord Adonis on 5 December 2008, the 50th anniversary of the opening of the first motorway in the UK, the Preston Bypass, now also part of the M6. It subsequently became one of the finalists for the Prime Minister's Award for Better Public Building (losing to Joseph Chamberlain
