- When the I-495 southbound on-ramp from I-90 eastbound and westbound is closed, traffic will be directed to follow the detour signs and use I-495 northbound to exit 59B (Route 9 westbound), to reverse direction back to I-495 southbound.
MassDOT is in the third of six stages toward completing a complete rebuild of the interchange. This stage is set to last until 2026, and will focus on completing the southbound ramps to I-495 from the Mass Pike.
