Motorway signage on the move

Parking in the HGV area of St Michael's Wood you do see some interesting things on occasions. This lunchtime I came across this lorry with two motorway information boards and the support structure for both.

Travelling past them I never gave any thought as to their size. However, seeing them up close, they are larger than I had given the designers and builders credit for.

This blip was taken on the southbound side of the M5, at St Michael's Wood Services.
