Creating some roads with terrain surrounding it

Hey there,

i'd like to develop my first JMonkey Engine game, it should be a simple racing game.

Until now i coud create a car you can control. My car gets an fixed speed value instantly the game begins.

The idea is now, to avoid some boxes at the road. That all works fine, the collision works, too.

But now i need tu create a road and a terrain, and I really do not know how to make that really simple and efficient.

Should I use a textured box with a texture as road, and the included possibilyto to create a terrein in JMonkey? Or should I do it some other way… I also have to create the sky etc, so there should be a Skybox right?

The grass should looke like this
