What happens next

Awarded 16 January 2026, started on site June 15 2026, CTDOT completion currently forecast July 26 2028; scheduled November road closures not themselves proof of removal completed.

What remains uncertain

Owner uses differing ramp naming in some lane-closure headlines, so record explicitly distinguishes permanent Exit 21 off-ramp removal from temporary Meadow Street on-ramp closure. Contract award is not a final delivered cost. Stage based on documented June site start.
