There is a one to two foot gap at the bottom of the barrier wall almost the entire length of Dover St. It allows noise and "fallout" from the vehicles on I-91 (n/b entrance ramp and roadway itself) into the neighborhood. Either needs to be filled in or dense plantings to fill the gap. There is a steep embankment leading up to the barrier wall full of overgrowth and dead trees. Lastly, at the bottom of the embankment, there is trash & debris piled behind some residences. It all needs to be cleaned up.
