Anyone know a quick way of building a curved viaduct?

I have a running session coming up in three days. Yesterday I went out to start clearing weeds, etc and found that a curved viaduct had collapsed .... probably the work of local wildlife. So I am now looking for a quick way of replacing it. The viaduct was eight feet long, a foot high and curved through about thirty degrees. The track is 45mm gauge.

Fast and dirty:
A part-sheet of plywood (or whatever) and a jigsaw..
Won't be pretty, but you should be able to get something functional, fairly quickly?

Plastic decking board? Several lengths cut at a slight angle and butted with joint plates beneath, or two planks' worth superimposed - won't be a smooth curve or pretty but cheapish and fairly quick as it can all screw together. This is a short stretch coming out of my shed, but I plan to use the same for a 2m 'S' shaped length elsewhere in the garden next year. One day I might get around to adding decorative foamboard masonry and ballast to disguise it a bit.

We had a lashed up viaduct on the Ruschbahn for a couple of years or so, as suggested ply for the arches with it nailed to decking more of which was also used for the track base. Was never very pretty but passed the muster for a while. As Martyn says, if you use plastic decking it could be the basis of something that could look much better when you are ready
 
I used standard 440 x 215 x 100mm Autoclaved Aerated Concrete blocks sold under the trade-name ‘Celcon’ to construct a 13-arch R5 viaduct on my layout. This ‘temporary’ structure has been in place 9 years!

I was going to suggest the same (ie Hebel in Oz) based on Greg Hunter's example

Not a quick solution but fairly cheap and very effective.
