MassDOT's project goals include to:

  • Reduce crashes in the project area for all movements
  • Reduce recurring congestion within the interchange
  • Reduce queuing that currently extends from the interchange onto the main lines of I-90 and I-495
  • Reduce travel time through the interchange, especially for high-volume movements

MassDOT has awarded a Design Build contract and preliminary work is beginning to prepare for construction
