Sound Wall in Prospect Park
As you can read here, there are folks in Prospect Park who are unhappy about the new sound wall along the west side of I-94.
I have heard these concerns as well, and shared them with MnDOT.
It's important to know some of the context as well. The residents on the east side of I-94 have been protected by a sound wall for decades, but until now those along East River Terrace and East River Parkway have not. I have heard concerns about freeway noise from those folks for years, as early as 2001. I have also heard that they're happy a sound wall has finally been installed.
I have asked MnDOT whether there are ways to break up the sonic reflection coming off of the wall. One interesting idea: what if we encouraged vines to grow on the side of it? Such a "green wall" would deter graffiti as well as damping some of the sound.
