Slippery surface sends child into bridge (7)

I believe the answer is:

skidpan

'slippery surface' is the definition.
(I've seen this before)

'child into bridge' is the wordplay.
'child' becomes 'kid' (synonyms).
'into' means one lot of letters goes inside another.
'bridge' becomes 'span' (synonyms).
'kid' going into 'span' is 'SKIDPAN'.

'sends' acts as a link.

(Another definition for skidpan that I've seen is " Slippery surface for training drivers".)
