This study analyzed several potential improvements to the I-89 corridor between Exits 12 and 15, including the Exit 12B interchange. While the study was initiated as an Environmental Assessment, it stopped well short of this and recommendations were made to proceed separately with several individual projects. Traffic projections and environmental screening were performed including potential wetland and archaeological impacts within or near the Interstate right of way (ROW), as well as potential air and noise impacts.
