The A74(M) & M74 run over 80 miles from the M6 at the Scottish border near Gretna to the M8 at Glasgow. This is one of the two most important routeways into Scotland from the south. The last stretch of the M74 opened in 2011 (see Link ).

A photograph of the wood burning power station near Locherbie. I needed to access this in a hurry and exposed my class to the excessive number of windscreen shots that blight the square which was embarassing. Posted this to allow quick access to the image.
