Talk about each week on main road? (6)

I believe the answer is:

seaway

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

'main road?' is the definition.
'seaway' can be an answer for 'road?' (thesaurus). I'm not sure about the 'main' bit.

'talk about each week' is the wordplay.
'talk' becomes 'say'.
'about' is an insertion indicator.
'each' becomes 'ea'.
'week' becomes 'w' (abbreviation).
'ea'+'w'='eaw'
'say' enclosing 'eaw' is 'SEAWAY'.

'on' acts as a link.

Can you help me to learn more?

(Other definitions for seaway that I've seen before include "Channel for shipping" , "Route for a vessel" , "Ship route" , "Inland route for use by seagoing ships" , "Channel open to ships" .)

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