Hamburg plans to build over highway
In Finland, roads cover a whopping 16% of all land surface area (buildings stand for 4%). In tax expenses for an average tax payer, the cost of upkeeping merely the state highways, means that only military defence costs, social security as a whole, export support and state loan expenses come close to this cost. Forget all about costs of education, environment, immigrants etc, – THEY DONT EVEN COME CLOSE. Verokuitti.fi
In Hamburg, Germany, they decided to do something about this.
For decades, the A7 motorway, a major north-south highway that connects Germany with Scandinavia, has been a headache for Hamburg residents. The expressway is loud, it creates a physical barrier between neighborhoods, and because it contains heavy truck traffic, it lowers the surrounding air quality. To solve these problems, Hamburg’s government arrived at a brilliant solution: cover the expressway with a large green roof.
