Is there any special name for ads which are placed along highways and especially I would like to ask for McDonald's as in the picture..
For example I would like to make a sentence like :
After you get on the highway, keep on driving .After about 30 minutes
you will see a huge McDonald's………

The example you show is a sign. specifically, it is an advertising sign (as distinguished from, for instance, a traffic information sign).
The "M" (double arches) on the sign is a logo. In the case of McDonalds, the logo is so universally recognized that the sign would be effective in drawing customers even if the sign did not include the McDonalds name.
It is not a billboard. As commenter pointed out, a billboard is a large flat panel (board); it is usually on supports to lift it high in the air for visibility. http://www.google.com/search?hl=en&site=webhp&tbm=isch&source=hp&ei=YMw9VbCtM8vWoAThhoDIBA&q=billboard&oq=billboard
