Why do some streets have to be closed for the construction of noise barriers?
In some locations, proposed noise barriers do not meet the cost-effectiveness criteria if the barriers were to be broken to allow passage of a street. Closure of the street is the only way to block enough noise to make the proposed barriers cost-effective. However, it is not TxDOT policy to eliminate existing street access. The City of Spring Valley and Afton Village subdivision proposed street closures in the proposed design when no other alternative for noise mitigation was possible.
