he Maryland State Highway Administration's sound barrier guidelines provide for the evaluation of sound barriers for communities adversely impacted by noise from state maintained highways. Sound barriers are evaluated in two separate categories: Type I and Type II.
General eligibility criteria apply to both types of sound barriers:
A sound barrier for new construction, or reconstruction, of a state highway. A community may be eligible for this type of sound barrier if it first meets the General Eligibility Criteria and the following Type I criteria:
A sound barrier along existing highways. A community may be eligible for this type of sound barrier if it first meets the General Eligibility Criteria and the following Type II criteria.
Sound barriers do have limitations. To work effectively, the barrier must be high enough and long enough to block the view of the road. Homes on a hillside overlooking a road; buildings higher than barriers; homes scattered too far apart and openings in noise barriers for driveway connections or intersecting streets are not good areas for sound barriers. In some cases, SHA can offer alternatives to help reduce noise levels.
