Ashton Viaduct, Cumberland-Lincoln, RI

The Ashton Viaduct crossing the Blackstone River
Usually a bridge like this has a lot of history behind it, but I can't even get a definite idea of its name. Some places call it the Ashton Bridge, some the Ashton Viaduct. I imagine it was associated with the nearby (like, if I turn to my right 90 degrees, it's right there) Ashton Village, which was once a thriving mill, so it must be at least a hundred years old, but... no information on how old it is.

I was biking on the Blackstone Valley Bikeway which stretches from Worcester, Massachusetts through to Cumberland, Rhode Island. I was just wanting to see how far I could get, maybe to where I grew up near Uxbridge, Mass., before we moved to New Hampshire. The Blackstone Valley was home.

Yeah, I knew the viaduct would be along the way, but still. I didn't come just for the bridge. Honestly.

The Ashton Mill
Told ya the mill was close.

Viaduct & bike bridge
The Ashton Viaduct is a five span open spandrel arch bridge crossing the Blackstone River, a river once called the most polluted river in the country with respect to toxic sediments, being used as it was as the industrial toilet for mills and factories from Worcester to Woonsocket. It is today still filled with pollutants. In that it shares a fate with the Housatonic River here in Connecticut -- enjoy at your own risk.

Neither river is likely to ever fully recover.

Not the Albion Bridge
Further along the bikeway, I found a pony truss bridge crossing the river. It looked in great condition, better than I'd ever seen one from the age of iron bridges. It didn't look to be one of the Berlin Iron Bridge Company's bridges -- most of theirs are lenticular.

Boston Bridge Works Builders
These bridges were built by the Boston Bridge Works... at least originally.

Turns out that Rhode Island  replaced the bridge, then bolted on parts of the old bridge so it would keep some of its old character. According to the contractor, Gordon R. Archibald Inc Civil Engineering,
To maintain the historic value of this river crossing, Gordon R. Archibald, Inc. developed the innovative concept of 'aesthetic rehabilitation.' Under this concept, the trusses were refurbished and placed astride a new, two-dimensional steel grid superstructure. The steel grid carries all of the new superstructure and vehicular loadings, leaving the trusses to carry only the weight of and loadings on the sidewalks. In this way, the reconstructed bridge can carry contemporary traffic loadings, while its 19th-century visual quality is preserved for future generations.
So I'm not sure how I feel about that. I guess it's good that they didn't just replace it with a slab of steel and concrete. They replaced it with a slab of steel and concrete and then put it in a dress.

Talcottville Iron Bridge, Talcottville, CT... again

Talcottville Main Street Bridge
I wasn't all that happy with my recent post about the Talcottville Main Street Bridge. First, I'd cleverly timed my photos just before leaves started opening, making a rather barren picture. Secondly, because I didn't even go on the bridge. I was already on the mill grounds and just shot it from there.

If I'd gone on the bridge and past it, I'd have come to the Talcott Ravine trails that connect to Vernon's branch of the Rails-to-Trails project. And I'd have seen the pond and gotten a much better view of the bridge -- with the water tower from the mill standing behind it, and the dam just past the bridge allowing the foliage on the banks of the Tankerhoosen River to show.

I'd have had the picture above.

The old bridge railing

This iron railing must once have been on the inside of the bridge, where steel guardrails now keep cars from slipping off the edge of the bridge. It was likely fastened on the outside to cover up the steel reinforcements that keep the bridge together. This bridge could really use a complete renovation. I'm not sure Talcottville is enough of a tourist draw to get Vernon to spend the million bucks or so to rebuild the bridge (I have no idea how much it would cost). Maybe if they find someone to buy the mill and do something fun with it, the bridge would get some love. Not while the mill slides forgotten into ruin, though.

First house built in Talcottville (1802)
So, if you want to see an incredibly historic bridge fixed up, come visit historic Talcottville. You can see the whole place in half an hour -- an hour and a half if you want to go down the ravine trails. There were some guys fishing in the pond, too, so bring your fishing stuff!

It's all about the Tankerhoosen, you know.

Talcottville Iron Bridge, Talcottville, CT

Talcottville Iron Bridge
This one's a local bridge -- it's right down the road, yet I'd never heard of it until today, when I ran across it while photographing the Talcottville Mill. It crosses the Tankerhoosen River just above a dam on Talcottville's Main Street. It's a pony truss bridge made, presumably, of iron.

The historic bridge site says this bridge was built by the famous Berlin Iron Bridge Company, and is the only pony truss bridge where the truss members actually bear the weight of cars crossing the bridge. A pony truss bridge, by the way, is one with no trusses connecting the sides along the top.

I was in my car, since I was coming back from a photography trip up in Shenipsit State Park, but this is a bridge that needs my bicycle on it.

Talcottville Mill
This mill was the center of Talcottville for decades. The Talcott brothers had bought the mill and the surrounding lands from Nathaniel Kellogg, who had named the area Kelloggville. No shortage of ego on either side, there. The Talcott brothers built twin homes across the street on hills, overlooking the mill. The mill remained active in some form through the 20th century, though it is all entirely abandoned now.

Just about time to recondition it into luxury apartments...

You can (and should!) read more about Talcottville's historic legacy, as the story it tells is repeated, with minor variations, throughout the northeast. Talcottville today is a historic district within Vernon, CT, and signs along the few roads point out and explain the historic significance of the mill and other relics of an elder age.
