Here is my best explanation:

'engineer' is the definition.
(Thomas Telford)

'cross after permit is rejected' is the wordplay.
'cross' becomes 'ford' (fording is a kind of crossing**).
'after' says to put letters next to each other.
'permit' becomes 'let' ('let' can be a synonym of 'permit').
'is rejected' says the letters should be written in reverse.
'let' written backwards gives 'tel'.
'ford' after 'tel' is 'TELFORD'.
