Railroad Bridge, Fredericksburg, VA

Railroad bridge across the Rappahannock River
I stopped in historic Fredericksburg, Virginia, on my way to visit my son this past weekend. Traffic along I-95 made it dark before I got to town, so I made sure to rise with the sun the next morning in search of the fanous Rappahannock River railroad bridge.

It's a concrete, eight (or so) span open spandrel arch bridge. The bridge is in active use by cargo and passenger trains; there is a beautiful Amtrak station just a block west of the bridge. It's a wonderful river crossing in its on right, but this is not the bridge that made Fredericksburg famous.

This bridge is very near the former site of an earlier bridge -- a bridge that was instrumental in one of the most one-sided battles in the Civil War.

In December of 1862, Union forces, desperate for a victory, were looking for a victory against Confederate forces entrenched in and around Fredericksburg. Blocked by the Rappahannock River, a tributary of the Potomac River, the two sides stared at each other until the Union Army could deliver sufficient pontoon bridge segments to build a bridge across the river -- which the army proceeded to do, under continual fire from the Confederates.

The Union army, encamped on the east side of the river very near George Washington's boyhood home, crossed the pontoon bridges, taking heavy losses, and entered into close combat with the Confederates among the streets and homes of Fredericksburg, eventually making a concerted effort to break the fortified lines on Marye's Heights.

They failed and were forced to withdraw. Union losses were twice those of the Confederates, a bitter loss that shook the North's already fragile support for Lincoln's War.

Fredericksburg today is an arts center for the area and home to the University of Mary Washington. It has a thriving night life and is extremely bicycle-friendly -- many of the city streets encourage bicyclists to use the entire right lane.

It also sports the second largest mall on the East Coast, the Central Park Mall, which makes travel on the outskirts of the city problematic during shopping hours.

Beautiful bridge, beautiful city.

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.

Railroad bridges, Hooksett, NH

Baltimore truss railroad bridge
I wasn't going to write this picture up. There's nothing particularly historical about this bridge. I didn't even know this bridge existed.

I'm on vacation, and I'd made a promise to visit my parents graves in Concord, New Hampshire, at some point during my week off. My dad would never, ever pay a toll if he could avoid it, and particularly on I-93 between Manchester and Concord. He'd always take the back road, Route 3A, through Hooksett and Bow and into Concord, where we lived.

That's how we kids were brought up. So I was toodling along on 3A, which follows the Merrimack River, just casually looking over now and again because it's a beautiful river and it was my river growing up. Through the trees, I saw an old iron railroad bridge and figured I'd better stop by.

I didn't recognize the truss design; I looked it up when I got home and saw it was a "Baltimore truss". The railroad bridges here in Connecticut all seem to be Pratt truss, so that was new.


This closed-off railroad bridge crosses the Merrimack nearly parallel to the Baltimore truss bridge. This one appears to be a three span Pratt truss bridge with extra bracing. Or it could be a Warren truss. I don't know. The cool thing is that these bridges, right next to each other, were made using entirely different designs.

Lots of people seem to have photographed these bridges (add me to that list) and/or jumped from them, but I'm not able to find any information about them online.

Just... back roads New Hampshire, I guess.
