MOTORWAY SIGNING

Advance direction signs on exit slip roads, other than diagram 2913.1, and the map type terminal roundabout sign on the main carriageway shown in diagram 2914 do not use the Motorway alphabet because destinations on the all-purpose routes are shown in panels of the appropriate colour and hence the Transport alphabet is used. Where a motorway terminates at a grade separated junction, the advance direction signs will be designed in the same way as for intermediate junctions. Panels are not used, and route numbers are in the Motorway alphabet. The map type roundabout signs shown in diagrams 2913.1 and 2914.1 are used where the roundabout connects two motorways. Motorway numbers on these signs are shown in the Motorway alphabet and coloured panels are used only if the signs indicate, additionally, a route that is not a motorway.

On map type advance direction signs on the main carriageway, the forward destinations do not normally include the motorway numbers. However, where the number of another motorway that can be reached from a junction ahead is shown in brackets, the characters should be from the Transport Medium alphabet and not the Motorway alphabet.

On gantry mounted signs, bracketed route numbers may be in either the Motorway or Transport Medium alphabet as appropriate. The general rule is that where the number is directly associated with an unbracketed number the Motorway alphabet should be used, as illustrated in diagram 2908. Where the bracketed route number follows a place name or is a destination in its own right, the Transport Medium alphabet should be used.

A combined junction number and distance plate (in Transport Medium alphabet) may be provided on sign gantries. The design of this plate is shown in figure 10-9. 96
