Corruption = bad roads? UPDATE

The question was posed here - how does corruption lead to bad roads?

An article over at Window on Eurasia provides some background.

First, Russian roads are bad:

• In the EU, "trucks carrying goods average 1000 kilometers a day" - in Russia, about 300.
• "In 1995, the country had 940,000 kilometers of such roads," a figure which has increased only marginally according to government estimates while independent observers think it has actually declined. Chine, by contrast, has 1,900,000 kilometers.
• According to the article, "in Kazakhstan, Uganda, Mauritania, and Lesotho, the quality of roads is higher”
• By WHO calculations, Russia is #2 (after Kazakhstan) in highway deaths.

Second, despite these points, Russian roads are incredibly expensive:

• This years budget slots $9 billion for road construction
• According to the article, one highway-kilometer costs Russians six times more than it does American taxpayers

The article ends with an unsatisfying explanation - “the answer which experts gives unanimously is corruption.” But who is doing the skimming and from where? If Russians are paying $9 billion per year to a highway grid that doesn't grow, it sounds like A LOT of money is being siphoned off. But which ministries? Tax, interior, transportation? More info please.
