I Love This Form of Advertising

Bridges in Kuwait are not that huge in fact they might be called an overpass for all I know. What I DO know is that they are the prettiest, most well maintained bridges I've ever seen. Since the Kuwaiti government does not take taxes from us to maintain the streets and highways, these bridges/overpasses are sponsored by any company in Kuwait, which in turn, paints the dull, grey cement a lovely colour (mostly light pastels) and adding the company logo (and sometimes their motto) on that bridge.
A good way to advertise and beautify.

Most bridges/overpasses I've seen in other countries are left unpainted, grey and rusty. Although the weather plays a role here, however they do collect taxes for their highways.
