Where slip roads leave and join at junctions within a road works site, the permanent arrangement for lane drop, lane gain and traffic merge may be temporarily changed. Signs may be provided to show the temporary arrangements.

The permanent layout might include a traffic merge with an acceleration lane. A distance panel may be added at the bottom of each sign
