Jack Arch Deck

View Exhibit map

A jack-arch deck is a specific variety of deck that was used on a number of bridges in the first couple decades of the 20th Century, and perhaps other dates. The jack-arch system is formed by creating an arch spanning between pairs of parallel iron/steel deck stringers, using brick, corrugated metal, or wood, and then pouring concrete on top. This encases most of the stringers in concrete, and provides a flat deck surface on top. New Hampshire produced a detailed discussion of them here: http://www.nh.gov/dot/org/projectdevelopment/environment/doc...
