The Sharon Town Offices have re-opened, as NSTAR has restored power to that building and the Sharon Fire Department, Town Administrator Benjamin Puritz said tonight.

Interim Fire Chief Dennis Mann said this morning that Irene-related power outages had forced the buildings onto emergency backup generators.

Besides the town hall, closed as of 2 p.m. were: Sharon Credit Union, the dentist office of Gerald S. Cohen and Alla Agamov, and Curves, all on Pond Street. Borderland State Park remains closed. The facility will reopen Tuesday.

NSTAR reported on its website tonight that around 162,000 customers remained without power as of 5:30 p.m.

Some residents told Sharon Patch today they've been without electricity for about 24 hours.

Mann said he had not heard from NSTAR regarding when service will be restored.

At the same time, Sharon's "major problem is that trees are down across wires that will take (NSTAR) crews to remove," Mann said.

"Of course, they're busy across the state," he said.

The Sharon Department of Public Works has blocked several streets due to hazards, including Moose Hill, Quincy, Richards and Mountain streets, Mann said.

However, Sharon Patch saw motorists driving around the Moose Hill roadblock and near or over a downed power line this morning.
