Old stone cold


Reconstruction at the Stackpole Bridge in Saco on Dec. 16. The pieces of concrete on either side of the arch are pre-fabricated T-wall structure which compose the upstream and downstream walls of the bridge. According to CPM Constructors Chief Financial Officer Tim Ouellette, the walls are being “back-filled” as they go up, which means that gravel is being poured into the structure and compacted. The metal rods protruding upward from the middle part will be surrounded by concrete, which will create a structure meant to add support to the original arch, Ouellette said, which remains in place. The bridge will be open for one lane traffic before the end of January, and construction progress is well on track for that goal. Ouellette said that the weather has been cooperative, in spite of cold temperatures the week of Dec. 16. The workers have used special heaters, sometimes called “ground thaw units,” to keep the ground and construction materials at a workable temperature while construction progresses. In summer 2016, the project encountered disappointment when an opinion was published that the reconstruction as planned would likely not qualify for listing on the National Register of Historic Places. The bridge was originally constructed in the mid nineteenth century. The opinion was in spite of the fact that the city spent an additional $400,000 on the project for the purpose of historic preservation. City staff plans to apply for the listing regardless of the opinion. (Anthony Aloisio photo)Reconstruction at the Stackpole Bridge in Saco on Dec. 16.
