best way to support elevated plates?

We're thinking about raising up half of our town, so that we can have the train
run into a tunnel and be a subway train on the elevated half and a surface train
on the other half (with the two halves joined by a hill).  This will also allow
us to make underground parking garages and whatnot.

Our town is composed mostly of road plates, with some other 32x32 green and gray
plates thrown in the mix.  Thinking about how to elevate and support these
stably has got me scratching my head.  We have plenty of Duplo for the columns,
but I need a surface under the plates strong enough for us to build on
(including not-too-gentle kids pushing down on things to anchor them to the
plates).

1x16 technic bricks cost about $0.20 each, and by my first design, I need about
20 of these for each road plate.  That's $4 just for the beams, plus the other
bricks and Duplo, which I haven't priced yet, but it probably comes to something
like $6 total.  So a 3x4-plate section of town would cost over $50 to elevate.

That's not terrible, but it's enough to make me hesitate.  Is there a standard
plan for doing this sort of thing?  Has someone evaluated different ways to
support big plates, and found a minimum-cost design?

Thanks,
- Joe

For my town I took the arches from the SAH site. Imagine looking at the baseplate. I placed two going north, one going east and west on the front and then depending on where they are in the tunnel I may have a total of 8 arches two in each (...)

(...) If you have lots of spare 2x4 bricks, then you can use the same technique we used at the 2002 GETS show: (URL) does use *lots* of 2x4 brick, and a few others, and you have to be quite careful to not leave large fractures in the structure, but (...)
