Contoocook Railroad Bridge, Contoocook, NH

Contoocook Covered Bridge
The Contoocook Covered Bridge, crossing the Contoocook River in the Contoocook village part of Hopkinton, New Hampshire, bills itself as the "oldest surviving covered railroad bridge in the world". That's a lot of qualifications, but it's still an impressive piece of covered bridge history.

Constructed in 1889 on the piers of an earlier bridge, it was built at a time when New England was turning to iron bridges, such as those built by the famous Berlin Iron Bridge Company. Its relative newness could be responsible for its longevity, maybe.

This bridge was probably designed by the Boston & Maine Railroad engineer Jonathan Parker Snow and built by carpenter David Hazelton. The B&M railroad used wooden bridges long after most other railroads had moved to iron.

Tradition. It's New England!

Double Town lattice
The Contoocook covered railroad bridge sports a rather unique double Town lattice construction, with a second lattice bolted to the outside of the first. This probably helped take the weight of trains as they came through to the nearby depot. I have not seen that in any other covered bridge, but Wikipedia claims it wasn't uncommon in northern New England and a few other examples survive to this day.

This bridge was used as a working railroad bridge to 1962, weathering a number of disasters, including the 1938 hurricane that nearly wiped out Providence, Rhode Island. Between 1962 and 1990 it was used as a warehouse. In 2006, the National Society for the Preservation of Covered Bridges paid for some necessary upgrades, and in 2010 the NH Department of Transportation modernized the lighting and fire suppression system -- you can see the red fire alarm button midway down the bridge wall in the picture above.

Portal to Contoocook Covered Bridge
I used to live twenty miles from this bridge when I was a kid, but I didn't know it even existed until a couple weeks ago. Used to ride to Hopkinton on my bike a lot after they built this really nice bike path that follows Interstate 89 north. But it would have been being used as a warehouse back then, anyway. The pictures on the Library of Congress website (which is down at the moment, so no links) show it filled with junk. Now it stands as the centerpiece and symbol of Contoocook village.


The bridge isn't hard to get to; if you're anywhere in the Concord, NH area, get to I-89, go north to route 127 and follow the road into Contoocook. There is parking available both at the adjoining depot and a restaurant on the other end of the bridge.
