Distinct width always once needed for restricted stretch of road (8)

I believe the answer is:
clearway
'road' is the definition.
(clearway is a kind of road)
'distinct width always' is the wordplay.
'distinct' becomes 'clear' (similar in meaning).
'width' becomes 'w' (abbreviation in geometry).
'always' becomes 'ay' (archaic term for 'always').
'clear'+'w'+'ay'='CLEARWAY'
'once needed for restricted stretch of' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for clearway that I've seen before include "where one must keep going" , "Stopping is not allowed on this road" , "No parking on it during certain hours" , "thoroughfare" , "area where you can't stop" .)
