MOBILE CARRIAGEWAY CLOSURE TECHNIQUES

NOTES: 145
 * 1) The specification for the works vehicle that closes the slip road is given in paragraph O11.8.5 below.
 * 2) If queuing vehicles may cause congestion at the entry to the slip road, additional warning signs will be required on the approach roads to the junction; see Section O11.5.
 * 3) In the hours of darkness, the area in the vicinity of the manually operated "STOP/GO" sign should be well illuminated, if necessary by means of temporary lighting. The "STOP/GO" boards must themselves be illuminated if used at night.
 * 4) Remotely operated signs may be considered to minimise the period that the slip road signs are displayed.
 * 5) Keys to the plan are given in Tables A1.4 and A1.5 of Appendix 1.
