Card game — bridge (7)

I believe the answer is:

pontoon

I believe this clue is a double definition.

'card game' is the first definition.
(I've seen this before)

'bridge' is the second definition.
(pontoon bridge is a kind of bridge)

(Other definitions for pontoon that I've seen before include "Lighter" , "'Flat-bottomed boat, card game and Mayo town (7)'" , "variety of bridge" , "It spans" , "Vingt-et-un" .)

I've seen this clue in The Times.
