Texture time!

Need some high quality seamless textures, been looking on the net and MB3D, CG TEXTURES, and SPIRALGRAPHICS have the best range of free textures.
I was able to create road tiles for rally game using PAINT.NET.

With a little trial and error the straight piece of road can create three different turn radii. So one straight tile and three corner tiles can make kilometers of road. Quick and simple.

Not bad for 5 minutes work.
This is how it works. For a bitmap 512 x 256, the canvas size is 4096 x 4096. The polar scale is equal to 2.00, this will give a 45 degree turn. Change the canvas to 2048 x 2048 and the turn becomes 90 degrees etc...The bitmap road and turn perfectly align, look at the pixel perfect alignment.

Remember can be used for chains etc...

Use a grid to make roads for tile pieces.
