A5266 existed in Telford between about 1975 and 1990, between the now-B5061 near Priorslee and the original route of A518 at Donnington via Furnace Road, Stafford Street, Gower Street, St. George's Road and Wrekin Drive.
Today, it is a nondescript urban single-carriageway road, and it seems an unlikely candidate to have once been of A class status.
Before around 1975, it was allocated the B5060 number, before that number was recycled for a Telford New Town road to the east.
