I-495/I-90 Interchange

Commonwealth Avenue Bridge Reconstruction Project Update

The I-495 / I-90 Interchange Improvements Project aims to provide a safe and efficient interchange of two of the most significant highways in the Massachusetts region. On an average day, about 75,000 vehicles use the interchange itself. In the immediate area, I-90 carries around 100,000 vehicles and I-495 carries around 110,000 daily.

The Massachusetts Turnpike (Mass Pike) 2016 conversion to All-Electronic Tolling (AET) has opened a window to improve conditions at the interchange for the first time since it was built in the 1960s.

Our goal is to improve safety and address chronically-deficient traffic conditions. Through these efforts, we will improve the movement of people and goods through the area - today and into the future.
