This is a Highway Overpass designed for Warhammer 40k Terrain. The pieces can be put together in numerous ways to make some creative line of site blocking terrain. I made the pillar pieces separate instead of one long piece as I intended to cut them apart, fill one end with putty to make it look like it is broken off. For the street part I added sand to the black paint to give it a more asphalt like texture.

For a full set you will need to print each file twice.
Use Super Glue to glue the two Highway pieces together.
Next glue the 4 runners under the Highway (using the support piece as a spacer.)
Then you can glue the support piece to the bottom of the Highway.
The pillar has a base that it fits in.

Don't be afraid to cut apart, and use pliers to rip up the pieces then fill it in with modeling putty for a great effect.
