D6.21.3 Where an exit slip road is closed, a suitable diversion route should also be signed on the main carriageway. The diversion route that is indicated will depend on whether solely a slip road or the full junction is closed and whether the destinations accessed from the affected junction can best be reached via the previous or following junction. Consideration should be given to erecting signs advising of the closure in advance of previous junctions. Variants of signs to diagram 2716 should be used in advance of the slip road and on the carriageway after the slip road to indicate the alternative route to be followed. An example of the signing required is shown in Plan SRC1.
Plan SRC1: Exit slip road closure
NOTES:
- Certain signs have been omitted for clarity.
- All coning is to Detail B.
D6.21.4 Where a motorway or dual carriageway entry slip road is closed a suitable diversion route should be signed. An example of the signing required is given in Plan SRC2. One option, if appropriate, would be to direct traffic onto the opposing carriageway to join the affected carriageway at the previous junction.
