 *one keep left/right" sign (610) at the start of the changeover; if this is placed in a closed lane, as opposed to a normally non-trafficked area such as the verge, a footway or a hard shoulder, then a "lane closed" barrier (7105) with a high intensity warning light should be added;
 * one "lane closed" barrier (7105) with a high intensity warning light and a "keep left/right" sign (610) at the end of the changeover;
 * one "lane closed" barrier (7105) with a high intensity warning light and a "keep left/right” sign (610) at the end of each lane crossed; and
 * where a temporary mandatory speed limit is in place, signs to diagram 670 should be continued from the lane-change zone; for the spacing of speed limit repeater signs, see Table 3.4, Note 1.

No relaxations apply.

A sign to diagram 7237 should be considered for single-lane changeovers where the changeover is below standard.
