River St. Bridge Redux

After already 'redux-ing' the diamond crossing of CP and CN under the River Street bridge, it's now time to improve my modelling of the aforementioned bridge. This was brought about by my grandsons' love of driving vehicles up and over the bridge when they visited my layout. The railings were the first to go, and having moved the scrap yard to the left of the bridge and considered expanding Anglin's yard into that space, I took a look at the topography.

Both railways' lines under the bridge are in a depression, and the CP was particularly poorly-drained and prone to flooding that made the ballast and ties sub-optimal. CN seemed to have a little better ballast and roadbed. My bridge, by contrast, arises out of complete flatness, so some scenic remodelling would be of primary importance in dealing with the bridge's approaches and abutments.

First, I copy-paste-printed several images of the bridge for modelling inspiration, three views looking south and two looking north (below). The drawback to the top four images is that they show the appearance of the bridge after the 1970 rebuilding. A concrete foundation was poured, underpinning the vertical wooden bridge piers and the road approaches. Comparing that to the fifth image, the roughness of the limestone, the gap where the bridge was raised during WWII, and the stone/vegetation of the supports become apparent. I was modelling circa 1970, but now I've backdated that to circa 1966, so I need to reflect that fifth image.

I'll post my progress here as the rebuild evolves...
