The St. Croix river bridge will be the starting point, today got it shaped up with the abutments and river banks created with screen and hydrocal:

I mixed this batch a little runny, haven't done this for several months so not surprised that I need to tweak my formula. No matter, for the base coat it isn't going to hurt anything, just take longer to dry. It is just aluminum screen with damp paper towels over them under the hydrocal.

It doesn't show up very well because of the color, however it will be painted and landscaped. I will be putting another top coat over the banks and a thin coat over the river bed so the wood does not show. The river bed will be painted hues of blue and green, sand and rocks on the shore, and vegetation on the stream banks. Rocks go inside the middle support, as the prototype was constructed.

The area around the abutments is roughed in. This material can be sanded.
Here is another look at the prototype. This photo was taken by Ron Nixon in april of 1950. This section of track was completed in 1901 and runs from Rush City, MN to Grantsburg, WI

It is a wooden truss bridge and could only support a small steam locomotive like the S-10 shown above.
Will be working on this area and the section of track that follows in the coming week
