TOPSFIELD - The Maine Department of Transportation is replacing two bridges in the Town of Topsfield in Washington County. The Farrow Lake Stream Bridge carries Route 6 over Deadman Stream, and the Flood Brook Bridge carries Route 6 over Flood Brook. Drivers should expect a one-lane alternating traffic pattern during the replacement of the Farrow Lake Stream Bridge. The culvert lining work on the Flood Brook Bridge will create minor traffic delays. This project is expected to be finished by mid-November. The contractor on this work is Soderberg Construction out of Caribou.
