In comparing the existing (2020) noise levels to the future (2040) noise levels, the PCI noise study concluded that construction of the interchange will actually decrease the number of impacted receivers from 54 impacted receivers to 26 impacted receivers. This is because the project includes building on and off ramps for the interchange at a much higher elevation than the existing roadway, which will act as a  shield from the interstate noise.

Overall, there were still 26 receivers that would be impacted in the PCI noise study area in 2040 (impacted receivers shown in red on graphic). The project team analyzed three potential noise barriers to lessen the noise impacts for these receivers; however, none of the barrier walls were found to be feasible and reasonable to construct. As a result, the PCI project does not include the installation of a noise wall.
