Just a quick little project I did in about 2 hours or so.
The model is untextured because the textures are from cgtextures.com
The model is already UV mapped, so if you would like to add the textures back on to it, here are the links:
NOTE: Download the FIRST image in the list.
How to re apply the textures:
Material "Road" : Under the material, click "Open" and select the image downloaded for road.
Any other materials with "Image texture" : Follow same for road, open the concrete texture.
There are a few parts with regular materials.
