M6 Junction 40
Junction 40 was opened in 1968, at the time Penrith had been a major bottle neck on the A6 north with a narrow one lane traffic light controlled section right in the town centre. To improve this the government brought forward the bypassing of Penrith earlier into the M6 program than they may have done. Thus on 7th November 1968 the Penrith bypass section of the M6 opened from a temporary junction just south of Penrith to junction 41 to the north. Junction 40 was the intermediate junction on this bypass. Junction 40 is a typical roundabout above the motorway junction however rather than 2 roads leaving it has 3. Before 1968 the A66 Trunk Road crossed the centre of the country from Penrith on the A6 to Scotch Corner on the A1 making an important east west link between the two main roads. In 1968 it was decided to extend the road east and west, East into Middlesborough while west through the central Lake District to Workington on the west coast thus making this an important cross country trunk road. The A66 crossed the M6 at junction 40 making it an important junction, Northbound it became the main junction for Keswick, Workington and the north lakes thus avoiding the slower route through Kendal and Windermere. Southbound it was the junction for Appleby, Brough and Scotch Corner and by implication the A1 south.The third road coming off the roundabout was an extension of the A592, which up until this time had joined the A6 just further south at Eamont Bridge, this was re routed along the track of a B road to meet the A66 just west of Penrith then from junction 40 roundabout the half a mile or so into the centre of Penrith, making the junction the main junction north and southbound for Penrith.
During early 2006 this junctions road markings have been reworked in order to improve the traffic flow more information can be found on the BBC website .
