This study examined the highway interchange of Interstate 190 and State Route 140 in Sterling, Massachusetts. Using data collected on-site as well as existing data from government agencies including MassDOT, the specific problem areas of the interchange were identified. Alternative designs were developed for the site characteristics based on industry standards and using engineering software. A single lane roundabout was recommended based on the criteria of safety, cost, and ability to meet future capacity demands.
