A way to get to the continent: une route involved with NL? (10)

I believe the answer is:

eurotunnel

'a way to get to the continent' is the definition.
(train from the UK to continental Europe)

'une route involved with nl?' is the wordplay.
'involved with' indicates anagramming the letters (involved can mean confusing or complex).
'une'+'route'='uneroute'
'uneroute' with its letters mixed up with 'nl' can make 'EUROTUNNEL'.

I've seen this clue in The Telegraph.
