The outside Rim that holds the manhole cover is depressed below the blacktop. So there is a big dip in the road. Whenever a big truck or a bus go over it not only makes a lot of noise, it also causes my house to shake a lot. It is in front of 827/829 Salem street Malden, Ma. I myself live at 844 Salem street and have reported this before however I didn't describe it well enough I think, so, nothing came of it. I am happy to talk if you want to call me about it.
