As of this week, Shattuck Street is closed to vehicular traffic from Market to Merrimack to allow for cobblestone restoration and some work on the gas main. This should take about 8 weeks.
Middle Street will be open to two-way traffic from Palmer to Shattuck for the duration of the closure. Shattuck Street sidewalks will remain OPEN during this process, and businesses will be accessible.
Further detail is available on Facebook, but basically the plan is to remove all of the cobblestones on Shattuck, excavate the road base, put in a new road base. and then bring back the cobblestones and reset them.
