From Tardis Wiki, the free Doctor Who reference
The A48 was a major road in Wales. It ran by both Bonvilston (PROSE: Bay of the Dead) and Cross Hands. (TV: The Categories of Life)
At least part of the A48 intersected with the M4 at junction 49. (TV: The Categories of Life)
In the late 2000s, Joe Hargreaves, along with his wife Jackie, was driving along the A48 from Llandaff to his home in Cowbridge when the pair were caught in a thick bank of fog. Joe crashed the car during a collision with a lopsided figure. (PROSE: Bay of the Dead)
The A48 appeared on Mary Cooper's map of overflow camps in and around Wales. (TV: The Categories of Life)
