TRENTON, Maine — Bangor Hydro-Electric Co. plans to begin installing an underground duct bank for electric facilities along the shoulder of the Trenton Causeway on Oct. 11 in preparation for installing new underground electrical conductors next spring. The project is designed to increase electrical capacity and improve reliability in the Mount Desert Island area.
The work this fall will include tree trimming and excavation work along the side of the road within the DOT right of way in the Trenton and Thompson Island area. No major traffic delays are anticipated, but there may be brief periods when traffic is reduced to one lane to allow construction crews to work safely.
In planning this project, Bangor Hydro has been working closely with the Maine Department of Transportation and Acadia National Park officials to ensure minimal traffic interference and minimal vegetation damage in the construction area. Although some small roadside undergrowth and softwood trees in the DOT right of way are likely to be affected by the construction, the Trenton Causeway is not expected to change in appearance.
“This is the first phase of our long-term plan to improve electrical service reliability in this area,” said Lisa Martin, manager of Transmission Development. “We evaluated many options to create a second electrical connection onto MDI, and have determined this design to be the best one in terms of cost, environmental impact, and ability to meet future customer needs.”
The duct bank installation is expected to continue through Nov. 15. Drivers in the area are urged to use caution.
