Bay of Fundy

With increased travel on State Route 1, the Maine Department of Transportation needed to install a culvert below the roadway at Mill Cove to prevent overtopping. The culvert carries tidal water and is exposed to constant wet/dry cycles.

Because of the corrosive saltwater environment, an Aluminum Structural Plate culvert was selected for the waterway. Clean, crushed and washed free-draining aggregate that was used during installation increased durability of the structure.

The culvert was inspected in 1973, 1992, 1996, 1997, 2000 and 2011 by MEDOT. Most recently, it was rated a 7 on a scale of 0-9 and remains in good condition.
