- if it is essential to cross the carriageway, wait for a gap in the traffic which is long enough to allow walking across briskly keeping a look out for oncoming vehicles. Be prepared to wait some time to do this in safety. On very heavily-trafficked roads it may be possible to cross the carriageway only during off-peak periods. See Section O3.5 and the HSE publication entitled "Crossing highspeed roads on foot during temporary traffic management works" (Construction Information Sheet 53). See References (Appendix 3).
O8.3.10 On completion of the work, the following should be observed:
- take special care when rejoining the traffic stream;
- ensure that the appropriate direction indicator is switched on before moving off;
- on a motorway, build up speed on the hard shoulder to match the speed of traffic in the lefthand lane before rejoining it. NB watch out for debris which can accumulate on a hard shoulder and may hinder its use; and
- the flashing amber beacon should remain in operation until the main flow of traffic has been rejoined.
O8.3.11 The "Surveying" plate variant to diagram 7001.1 is used for the protection of survey teams working on or very near the carriageway where the carriageway is not obstructed.
O8.3.12 On a heavily-trafficked road or where equipment is located on the carriageway, it will be necessary to close a lane using the principles set out in Part 1: Design, Sections D5 and D6 for single and dual carriageway roads respectively, so that the team may work in safety. Alternatively, it may be necessary to close one carriageway completely. This should be done by means of the appropriate layout of signs, including the "road works" sign to diagram 7001, delineators and barriers.
O8.4ROAD (HIGHWAY) MAINTENANCE INSPECTIONS/OPERATIONS
O8.4.1 This section refers to slow moving continuous operations such as highway maintenance inspections, road testing and white lining operations; see also Section O8.1 and Part 1: Design, Section D3.30.
O8.4.2 The requirements are:
- the work should be carried out at off-peak times;
- operatives should wait for a sufficient gap in the traffic prior to marking any defects on the carriageway. Section O3.5 deals with crossing the carriageway and specifically paragraph .O3.5.3 refers to safe gaps in the traffic;
- operatives should face oncoming traffic or use a lookout while marking defects; and
- where gaps in the traffic are insufficient, operatives should not attempt to mark the defect but instead should estimate the dimensions of the repair.
Work on three-lane single carriageway roads should be carried out from the nearside lane. If driving at speeds less than 30 mph or on lanes other than the nearside lane, mobile or static lane closure techniques are required.
