For the love of Bridges

Filed under: New Hampshire — Tags: , , — Miriam @ 6:45 pm

My dad is a Civil Engineer (You know he builds the structures that the Mechanicals destroy). I am grateful for this. As a kid when we went on vacation we would usually stop and visit interesting bridges, dams and lock system if there were any in the area.

While there he would talk to me about the static and dynamic forces at work in the structures of these marvels. An example, how triangles help make a bridge stronger with less material.

I always loved visiting bridges and locks with my dad. In 9th grade we wandered around St. Catharines exploring the abandonned locks of the older Welland Canals (the current one is number 4) for a class project. This included the discovery of a partially collapsed railroad tunnel.

I have always been fascinated by lift bridges. This is well known enough that my friends sometimes send me pictures of lift bridges they encounter while on vacation.

This is one of the reasons I love to go to Portsmouth as well. The Piscataqua river has at least three lift bridges that allow travel between New Hampshire and Maine.

The Memorial Bridge partially lifts every half hour between 7 am and 7pm in the summer months to allow smaller boat traffic to pass through. It obviously lifts completly on occasion for the big ocean liners to pass as well.

I do love lift bridges but I chose to focus my engineering career on the mechanical side because of my love for biomechanics. But I’m convinced that my early education in civil engineering is partially to blame. Developping an interest for science and math at a young age because I wanted to learn more has been incredibly valuable to me.

So thank you Dad!

  1. I love bridges, that’s why I love the old wooden covered bridges. Cause they were built without all of our current technologies and last so long. Some of the wooden trusses on those wooden brigdes are so thick I have to wonder where they got the big of a tree from.

  2. We don’t really have any sweet old bridges in Calgary – most bridges here are the normal concrete overpass type thing. I’m somewhat disappointed but the only things to cross are the river and other roads.
