I was on a mission during my recent hike along the Air Line Trail State Park. Having learned about the trail and the history of the Air Line Railroad I set out to find one of the engineering marvels I had read about, the Lyman Viaduct. A quick Google search for the viaduct will turn up all sort of images and some history. Originally built in 1873, the Lyman Viaduct carried a single track across Dickenson Creek supported by a wrought iron post deck truss design. It was over 1100 feet long and rose to height of 137 feet above the creek. A picture of what it looked like back in the day is shown below and reminds me of the classic train scenes one sees in old western movies.
It must have been a very impressive site to see, and the views afforded along the viaduct to train passengers must have been magnificent. As the trains became heavier, the structure became unsafe. So to support the heavier loads, the valley was filled in with sand and gravel, burying the entire trestle and preserving it intact. Even though it is easy to see pictures of what the viaduct looks like today, I needed to see it for myself. Here's what I found.

I know long time residents of Connecticut know all about this, but I find this fascinating. More pictures along the viaduct will be posted in the coming days.
