NZ120 Wooden Trestle Bridge

Building a bridge, again or still. When shopping around local dealers I came across thin wood & doweling in vast quantitys at ridiculous prices. So like anyone else I purchased what I needed to build a wooden trestle. Inspired by a bridge built by my granddad I went about creating one loosely based on the following photo's. Photo credit unkown.
The bridge area finally had a make over with 3 bags of 1kg plaster of paris being used to cover & shape the landscape. Mixing the plaster spoonfulls at a time into a container of water until all the water is absorbed allowed for a good 8-10 minutes of working time.

After plastering has been mostly used up, river is slowly built up in layers of PVA, water & colour pigment.

Showing the state of the current road, the plan is a smooth plastered road to mimic a far north rural road, with at least tarseal. The bridge arch road tunnel will be one way & coloured to represent the age of the bridge.. DCC Sound DE using the chassis from the DH..  

Showing the currently clay road, with a tunnel portal sitting in place on what could be part of a foundation. If only I can find the other tunnel portal...

The bridge in the rear will be a girder bridge, 3d printed in sections. of concrete pillar & steel construction. If I get that far..., then the wooden trestle could be replaced with something quite ambitious indeed!

Using some photoshop skills I've recreated the scene a few times & have a few pics with added backgrounds to share as a result.
