Motorway cantilever sign
A blue overhead sign suspended over the motorway from a post on the left, with a diagonal arrow pointing up and left, and the following text.
M54 [Solid circle diversion symbol] ; NORTH & MID WALES; Telford, Wolverhampton; Shrewsbury (A5).
Junction number: 10A.
The M54 was built to connect the New Town of Telford to the West Midlands, but now it's a major road from here to Shropshire and large parts of Wales.
