SLIP ROAD CLOSURE/SIGNING
O11.7.6 Comprehensive advance signing is essential to facilitate the temporary closure of entry slip roads. Depending upon the geometry of the slip road and the volume of traffic using it, the slip road can be closed at its downstream end, (Plans MCC2 and MCC3) or at its entry (Plan MCC4). See also Section O11.5.
O11.7.7 When a works vehicle is used to bring the slip road traffic to a halt, a manually operated "STOP" sign to diagram 7023, 900 mm in diameter should be used. The manner in which this sign is used is described in Section O11.18.
O11.7.8 If, following a risk assessment, the decision is made to use a works vehicle fitted with a lorrymounted crash cushion, the sign used on this vehicle is shown in Figure 11.2 below.
