Abutments were used to the left and/or right of tunnel portals to prevent loose rocks and debris from falling.
Abutments can be used as a stepped retaining wall to hold back loose rocks and dirt.
You can leave them bare (like newer wood panels) or paint a gray color (like weathered wood).
They are made out of Basswood. For this reason they can also be easily kitbashed into different lengths and hights by using a sharp hobby knife
