Massachusetts Street is once again fully open to traffic and parking after construction crews working on a downtown waterline replacement project removed barricades this morning.

Parking is now allowed on both sides of the 700 and 800 blocks of Massachusetts Street, and two-way traffic once again is allowed. The two-block section had been limited to one-way traffic for most of the summer as crews replaced century-old waterlines.

The streets were expected to not be fully open until Sept. 11, but good weather and extra work by the contractor allowed the project to move ahead about two weeks ahead of schedule, said Chris Stewart, the city’s interim director of utilities.

Minor work continues on the project, but it is not expected to impede traffic.
