PRINCIPLES OF DESIGN FOR THE END-OF-WORKS ZONE

Plan DZE1: End-of-works zone for a dual carriageway road

The principles are as follows:

• for works on dual carriageway roads with a permanent speed limit of 40 mph or less, a "road works" sign (7001) in combination with an "End" plate (645) is placed on the near side and off side of the carriageway, 45 m from the end of the works; for relaxations these signs are not required;
• for dual carriageway roads with a permanent speed limit of 50 mph or more, this sign is placed on the near side and off side of the carriageway, 90 m from the works; and
• if no temporary speed limit is in place the sign on the off side may be omitted

Exit taper:

• an exit taper with coning to Detail B at 45° to the carriageway is required, unless an exit is needed for works traffic in which case the cones may be omitted; see Plan DWA2 in Section D6.22.

Keys to the plans are given in Tables A1.4 and A1.5 of Appendix 1.
