This was a really cool project to be apart of. Just south of Spencer and I think it was just before (or after) slide zone 53. Below all the ballast and bedrock was an old culvert made out of old railroad ties.
The culvert collapsed and this was the project to remove and replace it with a new galvanized culvert. I included an old image taken in the very spot we were working. You can see the old remains of the bridge. 09/19/2019
