Neat little project: Thomas Brook Rail Bridge replacement in Oakfield, Maine. Sargent Corp. did a great job on this somewhat complex small job for the Maine DoT.
Removing and replacing a structurally deficient freight bridge involved a tightly sequenced shutdown on the busiest part of Maine’s Northern Railway. After removing tracks, the team had 14 days to complete work with only a single, 96-hour full outage of the crossing at a vital link in freight movement between Canada and the U.S.
Here’s the gist of it: They placed a 30‑ft‑span, three‑sided precast concrete arch on pedestals and spread footings within a 25‑ft‑deep excavation. It needed 67 precast concrete elements that were fabricated offsite.
They said it all got done “over the course of only a few days,” which was “a logistical and technical balancing act.”
Check out the post from ENR and see the pics. Very cool.
