Miles of Roadway Improved
RK&K completed a technical noise analysis for this multi-alternative NEPA project as part of the DEIS, then completed a study of the preferred alternative for the FEIS. The US 301 Project area extended from existing US 301 at the Delaware-Maryland state line to south of the Chesapeake and Delaware Canal in southern New Castle County, Delaware.
The conclusion of the analyses resulted in noise mitigation not being reasonable. However, because the project’s overall earthwork resulted in significant waste material, DelDOT proposed building berms. RK&K worked closely with the design teams to develop berms that would provide a visual screen while reducing traffic noise.
