SINGLE CARRIAGEWAY ROADS

The obstruction should be coned and warning lights placed. See Plan SC13, Case D. Two-way traffic past the obstruction should be maintained if possible, otherwise the road should be operated as an exit only from the roundabout and a diversion route signed for entering traffic. In this case, part of the circulating area should be coned-off to restrict traffic to one lane going towards this exit and advance warning provided using the "road narrows" sign to diagram 517. 146
