DUAL CARRIAGEWAY ROADS

D6.22WORKS ACCESSES AND EXITS

D6.22.1 Works accesses and exits are covered in Section D3.21. Care needs to be taken to ensure that signs are positioned so that they can be seen by road users and do not prevent works vehicles from accessing the site or exiting from the site safely.

D6.22.2 The principles for signing works accesses and exits are as follows.

D6.22.3 For works located on the near side of the carriageway of a dual carriageway road with a hard shoulder, entry to the works area is from the hard shoulder (Plan DWA1).

The principles are:

  • a "WORKS ACCESS ONLY 100yds"* sign (7306) is placed on the near side 100m in advance of the works access;
  • a "WORKS TRAFFIC ONLY” sign (7301 variant) is placed on the near side at the start of the works access, opposite the start of the entry taper;
  • a "WORKS TRAFFIC MERGING 100yds"* sign (7307) is placed within the safety zone coning adjacent to the near side running lane 100m in advance of the works exit; and
  • a "WORKS EXIT" sign (7302) is placed on the near side at the works exit at the end of the works.

If a risk assessment indicates that locating the site access just prior to the taper is likely to cause confusion then the coning in advance of the taper should be lengthened to 50m.

If the hard shoulder is of insufficient width for the required access, then access will be required from the single running lane past the works, see Plans DWAZ and DWA3. Works exit may also be required into the running lane, see paragraph D6.22.6 below.

*<nowiki>Signs to diagrams 7306 and 7307 may have the distances varied if required. {{anchor/n|D6.22.4}} For works located on the near side of the carriageway of a dual carriageway road without a hard shoulder, entry to the works area is from the safety zone in advance of the works area (Plan DWAZ). The principles are: *a "WORKS ACCESS ONLY 100 yds"* sign (7306) is placed on the near side, after the end of the entry taper, 100 m in advance of the works access; *a "WORKS TRAFFIC ONLY" sign (7301 variant) is placed on the near side immediately before the start of the works access; *a "WORKS TRAFFIC MERGING 100yds"* sign (7307) is placed within the safety zone coning adjacent to the near side running lane 100m in advance of the works exit; *a "WORKS EXIT" sign (7302) is placed on the near side at the works exit at the end of the works; and *coning to Detail B is used either side of the entry for works traffic. <nowiki>* Signs to diagrams 7306 and 7307 may have the distances varied if required.
