PITTSFIELD -- If you drive between Pittsfield and Burnham on Route 100/11, you'll need to find another way around starting next Monday.

State officials have set Sept. 15 as the start date for replacing the Neal Bridge in Pittsfield. The $594,000 state project should last 42 days, finishing up on Sunday, Oct. 26, state officials said.

During construction, that portion of the road will be closed to traffic. Message boards were set up today to alert motorists about the bridge closure.

The official detour route is Troy Road to Route 220 to Route 69. Normally, going from Burnham to Pittsfield would take about 20 minutes on Route 100/11; the detour will double that commute, to about 40 minutes.
