Knocked this up yesterday
Ideally it would have more pontoons (rafts) but for CD3 purposes it will easily fit the bill. Pontoon bridges this size can handle infantry and very light vehicles
The rafts came from the marine sets given to me recently by Col. I've got a few more but use them for other things
I'm going to add a couple of small details to finish it off and then a tad more paintwork, but it's more or less complete.
