The one-lane wrought-iron truss bridge will be removed from its perch over the Norfolk-Southern railway on Tuesday.
Remediation work to remove lead paint will be performed on the bridge, and then it will be trucked to Florida for a complete restoration. The bridge is 133 years old.
“It’s a community cornerstone,” said Virginia Department of Transportation spokeswoman Ellen Kamilakis.
Once the bridge is restored, it will be brought back to Nokesville and put back into service over the railroad tracks. A new concrete bridge will be built next to the old Aden Road bridge.

Built in 1882 for the Keystone Bridge Company, the truss bridge was purchased in the early 1900s and moved to Aden Road by Norfolk Southern, which transferred ownership to VDOT in 2014. The old truss structure showed substantial structural deficiencies, so a revised design was developed with the Virginia Department of Historic Resources and the community to allow the truss bridge to be rehabilitated as well as remain on the National Register of Historic Places.
The bridge was removed from the railroad crossing in January 2016. The new one-lane bridge opened to traffic in December 2016; it was closed temporarily in July 2018 to facilitate the truss bridge reinstallation and rehabilitation. The truss bridge was put back in place over the railroad in November 2018.
Some final detail work on the $8 million project will occur into the spring without major traffic impacts. The project is financed with federal, state and Prince William County funding. Norfolk Southern donated a construction easement to allow the work to be completed.
Sounds like Virginia! I assume that the beautiful Featherbed Lane-Variety Iron Works Bridge will receive the same haphazard treatment.
Nathan, can you scan and send me a copy in PDF Format? I cannot access anything from Europe because of privacy guidelines. I'm really interested in seeing what the bridge looks like. Thanks for your help! :-)

The outcome with this bridge, while indeed frustrating, is the best possible outcome, which prevented the total destruction of this bridge. I was a Section 106 Consulting Party on this bridge, as well as another truss (Featherbed Lane) in this same VADOT district. The engineer that handles this district of Virginia said that to keep a "two eyebar" truss bridge open to traffic in a load-bearing capacity, whether for vehicular traffic or pedestrian traffic is, and I quote "Russian Roulette." The engineer was severely critical of the preservation of such bridges in other states like Michigan, and Indiana.
On top of all that, contractors were allowed to dismantle this bridge in a way that severe damage was done to rivet holes (incorrect use of cutting torch).
Now that said, the Waterloo Bridge in Virginia is to be rehabbed, but (despite excellent condition) it will have a bunch of original materials replaced including all eyebars.
"Rehabilitation" can unfortunately offer way too many loopholes, shortcuts and compromises when compared to "Restoration".
That’s a shame. Better than nothing I guess.
Looks as though the trusses are non-functional at this point.

Alright so, after being restored and repaired in Florida, the bridge is apparently going to be reinstalled near its original location, so far presumed to be for vehicle traffic once more. I don't know how much historical integrity had to be compromised for its repair since it was claimed there was major damage that had to be repaired, but it has been repaired and is scheduled to be reinstalled sometime next year probably. A far better fate than many old rail-crossing road bridges.
Well, never mind the rehab and reopening... as of late last year VDOT claimed that the restoration work needed was far more extensive than thought, so it appears by photos that they thew up a new concrete eyesore in its place. The historic bridge is supposed to have been preserved elsewhere but I can't find an article that confirms if this actually happened.
Passed underneath on an Amtrak journey just now. Doesn't appear to have been put back in place yet, but so glad to hear of its positive fate.
Nathan,
I was mostly joking. They are significantly reworking the crossing and approaches while preserving the historic bridge. The problem is when using this as a reference, the cost may scare others away. I think a better number to use is the incremental cost increase of preserving the bridge.

Art: A few clarifications. First, this is a rehabilitation, not a restoration. Second, the project includes construction of a NEW one-lane bridge (including superstructure and abutments) next to the historic bridge. Third, this will require substantial work to the approaching roadway to accommodate the one-way couplet configuration. Fourth, this project includes the replacement of the existing abutments for the truss with a revolutionary hammerhead abutment design that increases the available space for railroad tracks under the bridge, while not requiring the truss itself to be lengthened. Fifth, this is a DOT bid project, and so like any DOT project you can expect higher per-foot costs, plus costs for DOT oddities... one VDOT project I evaluated included an on-site office trailer to be provided... cost of site trailer: $70,000.
So as you can see, taking all of this into account, you can see how you get up to this project cost, and why the project is a lot more expensive than say, just as a random example, the cost for a historic bridge restoration specialist to restore a 137 foot truss bridge in a non-DOT setting.
I maintain that this is one of the best examples of Section 106 I have ever been involved with, and the solution for this bridge is one of the most creative I have encountered. If all projects involving historic trusses were approached with the open mind and creativity of this project, we would have a lot more success stories in this country.
$5.77M to restore a 5 panel pin connected truss! I predict that they will be gold plating it to prevent corrosion.
We visited this bridge last year. Glad they are being creative.

Yes, this bridge is not at risk. I was a consulting party for Section 106 Review. Its the first time EVER where I have been 100% happy with the way a Section 106 Review was conducted. They entered the process with an open mind and came up with a creative solution that avoided adverse effect. The bridge will sit on new, unique hammerhead abutments that will increase space between abutments for the railroad below while avoiding the need to lengthen the truss!
I was very pleasantly surprised ( especially since it's VDOT) to read in this same article that the truss bridge will be strengthened (not replaced) as part of a project to turn it into a one way couplet, with a new bridge being built alongside of it to handle traffic in the opposite direction.
It is common (and often required by federal law) to offer a historic bridge slated for demolition to a third party. This however is not a preservation committment, and if nobody steps forward to take the bridge (which is the most common scenario) than the bridge would face demolition. I have however learned that Section 106 has not yet been conducted for this bridge, so VDOT is premature in describing this as a replacement project, before they have considered alternatives to avoid adverse effect.
It looks like they are considering relocating the historic bridge if a party comes forward to take it.
Tony,
You assume correctly, Featherbed will be placed on steel stringers. Again, we have a "best possible" outcome, as the Consulting Parties added this alternative, which places the truss on steel stringers at existing width with one pier. Original proposals were adding "thru girder" beams (which would have blocked view of trusses), and another which would have widened the truss (destroying the Variety Ironworks design of overhead bracing).
