M90 motorway 2.69

The M90 is a motorway in Scotland. It runs from junction 1a of the M9, at the south end of the Queensferry Crossing, to Perth, passing Dunfermline and Kinross on the way. It is the most northerly motorway in the United Kingdom, the northernmost point being a spur into the western suburbs of Perth at Broxden.HistoryThe first section of the M90 opened in 1964 to coincide with the opening of the Forth Road Bridge and Masterton junction (junction 2). The next section, Crossgates – Kelty and Cowdenbeath Bypass, opened on 1 December 1969, with the next section, Kinross and Milnathort Bypass, opening in May 1972.The final two sections were due to begin construction around 1973/74, but due to the oil crisis, were put on hold. The next section from Arlary ( Jct 8 with A91) to Arngask was opened in March 1977, with the final section between Arngask (GlenFarg) and Muirmont opening in August 1980; which connected up with the completed Friarton Bridge and Perth Bypass to Broxden.DetailsThe M90 leaves the east-west M9 in the vicinity of Kirkliston and heads north. Previously the motorway was interrupted by a stretch of the A90 but with the opening of the Queensferry Crossing there is now continuous motorway from the M9 to the terminus near Perth. The crossing opened as part of the motorway on 30th August 2017, although there is currently a 40mph speed restriction across the bridge (which will be lifted by the end of October 2017).
