DUAL CARRIAGEWAY ROADS

Guidance on the design of the crossover and changeover is given in Sections D6.5 and D6.6.

For principles for the changeover see Plan DZE2.

For principles for the crossover see Plan DZE3.

For crossovers with a sharp deviation; see paragraph D6.5.3.

Where the road’s permanent speed limit does not change within the works site, a sign combining the signs to diagram 7001, 645 and 671 or 670 on a yellow background should be used on both sides of the carriageway to mark the end of the road works and all associated restrictions, in place of the signs to diagram 7001 and 645. Where the permanent speed limit does change terminal speed limit signs are required (see paragraph D6.19.3). 224
