Paver content to announce new street (6)

I believe the answer is:

avenue

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

'street' is the definition.
(I know that avenue is a type of street)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for avenue that I've seen before include "A broad wide street" , "Wide street or road as in New York" , "A line of approach" , "Broad tree-lined road" , "Road leading to a house" .)

I've seen this clue in the Sydney Morning Herald.
