Traffic was allowed to flow all the way down Boylston Street on Wednesday morning for the first time since two explosions on April 15 killed three spectators and sent more than 260 to the hospital.
Delivery trucks made their way down the street under a heavy police presence.
Workers at some businesses and hotels in the area were allowed to return to their jobs on Tuesday to prepare for reopening.
Some stores directly affected by the blasts are still boarded up.
The Copley subway station that had been closed since the bombings also reopened, while the main branch of the Boston Public Library also was scheduled to reopen Wednesday.
