Construction activities are in progress. Weather and unexpected circumstances make all construction activities subject to change without notice, but we will do our best to keep you updated.
Phase II Traffic and Construction (January 2025 – Winter 2025/2026)
Phase II of the project began in January 2025 and includes the replacement of the south side of the Maffa Way Bridge and the north side of the Mystic Avenue Bridge. MassDOT implemented traffic shifts on both the Maffa Way Bridge and the Mystic Avenue Bridge in January 2025 to accommodate Phase II construction.
On Mystic Avenue, two lanes of traffic are shifted to the newly constructed south side of the bridge. On Maffa Way, two lanes of traffic are shifted onto the newly constructed north side of the bridge. One lane from Broadway in Somerville and one lane from the I-93 ramp will be maintained. Pedestrian access will be maintained across the bridge.
On the Maffa Way Bridge, vehicular travel is reduced to two lanes and the south side of the bridge is closed for construction.
On the Mystic Avenue Bridge, vehicular travel is reduced to two lanes and the north side of the bridge is closed for construction.
Vehicular and Pedestrian Detours for Phase II
In order to establish the work zones for Phase II, the following local detours were implemented in January 2025 and anticipated to remain in place through January 2026. Appropriate signage and messaging will be in place to guide drivers through the work areas.
