NOTES:
- Certain signs have been omitted for clarity.
- All coning is to Detail B.
- If the curvature of the exit slip road is severe, the use of signs to diagram 606 and 7104 should be considered.
D6.21SLIP ROAD CLOSURE
D6.21.1 Before the option of a slip road closure is chosen, the consequences to drivers in terms of the length, quality and signing of the diversion route should be considered.
D6.21.2 It is good practice to give advance warning of the closure indicating the time and date when the slip road will be closed, for example, using the sign to diagram 7002B (see paragraph D4.12.4). Publicity is dealt with in Section D3.40.
