DUAL CARRIAGEWAY ROADS Entry taper for a dual carriageway road with a permanent speed limit of 50 mph or 60 mph

Principles for entry tapers are:
 * length of taper is 150 m/lane closed;
 * coning to 1.5 m spacing, Detail B – see Table A1.5 (Appendix 1);
 * one "keep left/right" sign (610) at the start of the taper;
 * one "lane closed" barrier (7105) with a high intensity warning light and a "keep left/right" sign (610) at the end of each closed lane of the taper; and
 * one "lane closed” barrier (7105) with a high intensity warning light every 50 m along the length of each closed lane of the taper.

Principles for entry tapers for works for which relaxations apply are as for standard works except: 174
 * coning to 3 m spacing, Detail C2 – see Table A1.5 (Appendix 1); and
 * the "lane closed" barrier (7105) with a high intensity warning light every 50 m along the length of each closed lane of the taper may be omitted.
