Other stretches of interstate have noise barriers (large concrete walls that reflect the sound). These sound barriers have also been known to keep out more than just sound, but also cut down on pollution (http://www.boston.com/news/local/massachusetts/articles/2009/12/20/highway_barriers_block_much_more_than_sound/). If you aren't familiar with sound barriers, and if you live in the midlands, just take a quick trip down I-20 between I-77 and Spears Creek Church Rd., where the widening project is taking place. Not only is the interstate getting wider, but they are also installing sound barriers. Now, if the residents in the Clemson Rd. area of Northeast need sound barriers, then so do the ones in Woodfield!
