Where to find traffic making encroachment (7)
I believe the answer is:
inroads
'encroachment' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for inroads that I've seen before include "Major acts of encroachment" , "Ordains as offensives" , "Hostile incursions" , "large quantities consumed when these are made" , "advances" .)
