About the interchange
For years, the I-495/I-90 Interchange has experienced traffic demands exceeding its capacity. On an average day, over 100,000 vehicles travel on both I-90 and I-495, with about 75,000 vehicles traveling through the interchange, including approximately half of all trucking entering eastern Massachusetts. The deficient geometry concentrates movements through the former toll plaza area, resulting in queuing onto the interstate mainlines and crash rates twice the statewide average. Through this project, we will improve the movement of people and goods through the area - today and into the future.
