Starting Friday at 10 a.m., Fremont Street will be closed from Howard to Mission Street. It's all part of the construction of the new Transbay Transit Terminal.
Similar work was done on First Street in May. Workers will dig out the roadway and place a steel bridge. That will allow them to excavate and build the underground terminal without more closures.
The roadway is expected to reopen in time for Tuesday morning's commute.
