Each of the border stones carries a plaque to commemorate the completion of the project and a large white or red rose marking the boundary between the old counties of Lancashire or Yorkshire - a reminder of the historic rivalry between the Wars of the Roses houses of York and Lancaster. The markers further reference the motorway’s surroundings through the use of local Pennine aggregate and stone in their construction.
Alan Shepherd, National Highways’ regional director for the North West, said: “Cultural heritage and conservation is important to National Highways and we are always willing to work with stakeholders such as Historic England to ensure we preserve sites of special historic or cultural interest near our roads.
"It’s very pleasing to have these marker stones listed – it’s is a tribute to all those roadworkers in the ‘50s and ‘60s who paved the way for our 21st century motorway network.”
And Simon Boyle, director for Yorkshire and the North East, said: “Tens of thousands of drivers use the M62 every day. It’s a lifeline for communities and an artery of the economy.
"We’re delighted the boundary markers between the old red rose and white rose counties have been recognised in this way.”
The M62 now runs between the port cities of Liverpool and Hull linking other major towns and cities like Warrington, Manchester, Leeds and Huddersfield along the way. It plays a vital role in the economy of the North and the rest of the UK.
It is the only trans-Pennine motorway in the country. A road sign at Windy Hill, within the cross-border section between junction 21 and junction 22, also marks the highest point of any motorway in England at 372 metres (1221 feet) above sea level.
Historic England announced yesterday (Tuesday) the marker stones had been given Grade II listed status to celebrate the Queen’s Platinum Jubilee. Five buildings across the country, including the Sun Pavilion and Colonnade elsewhere in Yorkshire at Harrogate, have also been listed.
