TSRGD ref : 520
From : 1964?
To : Present
Variants : similar to Road Narrows

Pre-Worboys sign

No examples of pre-Worboys signs marking the imminent end of a dual carriageway seem to survive. However, as dual carriageways existed from the 1920s, if not earlier, many would have ended without the benefit of a roundabout, traffic lights or give way junction. A worded information sign stating 'End of Dual Road' was often provided.

Worboys Report sign

The sign designed in c1964 for the Worboys Report is very similar to the double-sided Road Narrows sign. Indeed, the main difference is the thicker widths of the black lines, and the two being pushed together so that they meet in the middle. Perhaps it is this similarity that has led a number of highway authorities to mistake the two and use this sign in error for 'Road Narrows'.

The sign is generally used on the approach to the end of the dual carriageway, with the Two Way Traffic sign being used at the point where the dual carriageway ends.

Irish sign


The equivalent Irish sign is coded W 095 in the Department of Transport's Traffic Sign Manual.

On older Irish dual carriageways it is often the case that this sign was accompanied by a worded warning sign due to the then relative rarity of such roads in the country.
