roadworks

I'm a little stuck... Click here to teach me more about this clue!

'what may hold drivers up' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'saw dork or drunk' is the wordplay.
'drunk' indicates an anagram.
'saw'+'dork'+'or'='sawdorkor'
'sawdorkor' with letters rearranged gives 'ROADWORKS'.

'showing' acts as a link.

Can you help me to learn more?

(Other definitions for roadworks that I've seen before include "holding up travellers" , "Street repairs" , "reason for traffic hold-up" , "What delay motorists" , "They hold traveller up" .)

I've seen this clue in The Times.
