New York is in the process of building a new bridge – actually two separate spans – to replace the existing Tappan Zee bridge. The new bridges will be cable-stayed. The old bridge, the longest in New York State, is a cantilever bridge. It crosses the Hudson River at its widest point. It was built in the early early 50’s, and because of a lack of material due to the Korean Conflict, it was built as inexpensively as possible. The current bridge is nearly 60 years old. The approach to the raised span is nearly water level. I remember crossing the bridge many times as a child, always a bit leary about how close to the surface we were.
Work on the new bridge is underway. We’ll be tracking the new work while also taking a look back and the construction of the original bridge. I don’t know about you, but I’m definitely looking forward to this.
