UPDATED Aug. 11, 3:10 pm: Commonwealth Avenue and the BU Bridge reopened to traffic on Saturday, August 11. Final “finishing work” will occur during off-peak hours in the days and weeks ahead.
The MBTA Green B Line will resume normal service between Blanchard and Babcock Streets for the Friday, August 10, afternoon rush hour, the state announced.
The Commonwealth Avenue and BU bridges will reopen to all traffic Saturday, as workers finished replacing the Comm Ave bridge.
Friday’s announcement by the Massachusetts Department of Transportation (MassDOT) did not specify the time of the bridges’ reopening Saturday. The Green Line’s service resumption will come ahead of schedule, as the state had originally planned to resume service Saturday at 5 am.
“We are pleased to be restoring MBTA Green Line trolley service today…and lifting vehicular travel restrictions on the Commonwealth Avenue bridge and the BU Bridge on Saturday,” said Jonathan Gulliver, MassDOT highway administrator.
“We have appreciated the cooperation and support from the traveling public, business owners, and local community throughout our operations,” he said.

Construction crews used accelerated bridge construction techniques—working 24/7 with prefabricated girders and concrete deck panels—to replace the Comm Ave bridge’s westbound lane. The state replaced the eastbound side last summer. The 53-year-old span’s age had left it structurally deficient.
The hyperfast techniques shaved what the state says would have been a four- or five-year project down to roughly a month over the two summers.
Work proceeded so smoothly that the Massachusetts Turnpike, which threads under the Comm Ave bridge and had lane closures to accommodate the construction overhead, reopened all lanes one day ahead of schedule on August 5.
MassDOT advises the public to use caution when passing through the area while workers put finishing touches on the project. …
