The team, who work with one of the largest geographic databases in the world that is updated over 10,000 times a day, has also worked out that if you drove non-stop, day and night, the entire length of our road network, all 215,490 miles of it, and you travelled at an average speed of 40mph, it will take you 224 and a half days.
If you were to attempt this at London’s average speed of 9mph it would take you almost two years and nine months to travel every road in Great Britain. In a driverless car, which has an average speed of 11mph, the journey would take just under 2 years and 3 months.
Ron Andrews, spokesperson for Ordnance Survey, said: “We make over 10,000 changes a day to the geographic database of Great Britain and are looking forward to recording the new roads and the changes to existing ones that are planned.”
Britain only needs to add another 5,363 miles to its road infrastructure to have enough to reach up to the moon when it is at its closest on its elliptical orbit.
