The southern part of the Back Cove Trestle that runs between Portlands East End and the B&M Beans plant will be demolished. It has become a hazard to boaters as it continues to deteriorate, loosing pieces into the water.
https://www.pressherald.com/2020/11/22/state-to-demolish-part-of-historic-train-trestle-in-portland/Maine Narrow Gauge RR tracks end at the West end (RR south) and they had expressed thoughts of regauging and crossing it.
Here are a couple of Google images. The first is a picture of the south end, the second being the overall trestle. MNGRR is to the right, the B&M plant is on the left.


And here is a video shot in 2019, that really shows some of the deterioration.
