Moving along a little faster now (hopefully) - got foam on four out of six modules, and have picked up some Woodland scenics .5" and 1" risers, some 2% inclines for the track subroadbed once all six modules have been covered in foam.

I have also ordered bridge kits for the four bridges (3 road bridges/overpasses and 1 RR river bridge - reference numbers in circles on drawing).
This is what I chose:
1) Road overpass ("River Yard Overpass") - sort of inspired by the Lyndale Avenue Bridge crossing over Great Northern and M&StL tracks in Minneapolis, made by putting together a 175' (24" in H0 scale) overpass from two Rix 150 foot Vintage Highway Bridges.
2) Road overpass ("Third Street Overpass") - inspired by this prototype photo: http://collections.mnhs.org/visualresour...eid=130586, showing a two lane road truss bridge spanning over a single RR track.
I am hoping that the Walthers double span truss bridge will be a reasonable approximation (with a road deck added).
3) Landwards spans of river crossing road bridge ("Cedar Avenue Bridge") - I considered several options here, there was no shortage of beautiful Mississippi River crossing road bridges in Minneapolis in the late 1950s, in many different styles.
I was tempted by both of the two furthest away bridges in this picture: (http://collections.mnhs.org/visualresour...eid=201276), but in the end I just landed on "use the last two 50' sections of the second Rix 150' kit), and say we have a reasonable approximation of the landwards spans of the second bridge from the front" (which can be seen better in this picture: http://collections.mnhs.org/visualresour...eid=112893.
4) Mississippi River railroad bridge. Long (for my layout - almost 40") bridge. I don't want to try for something like the stone bridge - too iconic - wouldn't look right here. So I looked at this prototype photo for inspiration: http://collections.mnhs.org/visualresour...eid=188605
The near bridge, which seems to be a combination of a deck girder and a truss bridge, seems more interesting, but it is probably safer on a liftout (that can get bumped during a session), and just put together a bridge similar to the one in the background - in this case made from two Walthers single track thru truss bridges.
I am already looking forward to my bridges in the mail in a couple of weeks :-)
Now - back to gluing foam and using inclines and risers !
