The A7 bisects the northern German city of Hamburg. The A7 is also one of the largest and longest freeways in German and keeps getting busier and louder. It’s becoming so loud that its breaching national noise pollution levels and a new idea to make the highway quieter will soon be reunifying neighborhoods throughout Hamburg. City officials have decided to essentially burry large chunks of the A7 to cut down on noise, building parks on the top of tunneled freeways. The parks will bring the neighborhoods back together and eliminate the nasty highway noise at the same time. The tunnel-park project will be completed sometime in 2022.
