^ Is it possible they're nipping at the top course in order to add the side bike/ped space?
Maybe if the stones are salvaged they can be cut down as pavers for the long-term work to convert Canal Street into a pedestrian mall. Alternatively, the same could be done for future pedestrian space at Blackstone Market/Haymarket; Downtown Crossing pedestrian-improvements (raised crosswalks, places to sit, paved shared streets); or an upgrade to the Public Garden asphalt ring around the George Washington Statue, be it places to sit, climb, or walk across. An adaptive reuse of the stones might actually be a thoughtful use for the latter two suggestions as DTX is Washington Street and the Public Garden has the Washington statue (nod to North Washington Bridge).Yeah...the abutments have to go for boat traffic. Old vs. new placements don't agree with each other for lining up a straight channel into the Charles locks.
As for preservation? Well, the stone blocks themselves are individually quite valuable if they can be chipped out intact. So depending on condition and what you can cleanly separate from the mortar they might be able to salvage some of that for future use elsewhere.
Salvaged stone masonry was used in the reconstruction of the Longfellow Bridge. The stone, Rockport granite, was salvaged from the Amesbury Derek Hines Bridge when it was dismantled a few years ago. Rockport granite hasn't been quarried since the 1930s, so the salvaged stone was the only way to match the look.I was talking about the bridge "abutments", which in bridge terminology are on the ends of the bridge. The bridge piers (not the abutments) are in the river. I know the bridge piers had to go because of the reasons cited here, but the bridge abutments, in my opinion, could have been incorporated into the ends of the new bridge.
In any case, the stone masonry on the abutments can be salvaged and the stones removed intact. I was involved in several projects where large stone masonry walls (granite blocks joined with mortar) were successfully taken apart and reused. These walls were from the 1920's. So it is doable. The stone masonry piers in the water are a different story, and might be too difficult to disassemble.
