High Quality Content by WIKIPEDIA articles! The A500 is a major primary A road in Staffordshire and Cheshire, England. It is dual carriageway for most of its length and connects Nantwich, junctions 16 and 15 of the M6 motorway with the city of Stoke-on-Trent. Because its shape between the motorway junctions resembles that of a capital D, it is known locally as the D-Road (D is also the Roman numeral representing the number 500). In 2004 the road was stated as carrying 60,000 vehicles a day through Stoke.
