rrnut282 Modelcar: BaltACD: Why is it I feel more secure traveling over bridges that were overbuilt 100+ years ago than I do traveling over today bridges that are built to the structural engineer's calculated minimum requirements. They had a lot more fluff factor in their minimums back then because they had no solid data on material's ultimate strength. Today, engineers design to the dollars available. Modelcar: ....What a beautiful photograph...! The low sun really made it dramatic. And I can see why the bridge has survived over that time frame and still looks so very sturdy. Probably way overbuilt with structual materials. Isn't that the truth. Wish we {our country}, could afford to built then that way now. Interstate bridges falling apart in 30 - 40 years. Example: Right here in Muncie we have a 4 lane overpass built perhaps 25 - 30 years ago. Right now, it is being dissambled to be replaced. Prestressed concrete beams. Deteriorated at the ends so badly, the structual metal rebar are exposed and all rusted. Concrete falling away in chunks. Tillotson over the former NYC??

Yes............That's the one. I took pic's of it about 3 years ago and it looked pretty nasty then.

....Speaking of Railroad {overbuilt}, bridges. Right here in Muncie, there is a 2 span thru truss bridge standing that was abandoned back in the early 1970's. I don't know how long it has been there, but I'd wager it's approaching or is 100 years of age.
It is a heavy built structure similar to the one in beautiful photo we've been commenting on, and it appears it will stay there another 100 years, if the center masonary support stays in place.

Outstanding photograph. Probably the most impressive that I have seen in a long time.
As to the age of the bridge and the comment by BaltACD: I was one of the Police Officers directing traffic at the ribbon cutting of the new Jefferson Avenue Bridge over the Mill Creek yards in 1963. A little over 30 years later, the bridge was condemned and torn down. Such is modern engineering.

DadgariPhotography Thank you all for taking the time to look at this photo. I'm glad some of you enjoyed the photo enough to comment on this thread. Quentin, this image is actually a longer night exposure of a train's headlight passing through the bridge. The sun had set about 4 hours prior to this photo being taken. Thanks again,

Thanks again,
I paused for some time to decide whether it was a timer and a headlight or sunset. Believe I decided I didn't see any indications in the water of it being a time exposure, but guess I made the wrong decision. I still say it's beautiful...!
And I should have noticed the two light "streaks" low on the bridge from the passing train.
Edit: Wife Jean just walked in here {and brought me some icecream}, and surprised,...as I had the picture on full screen....She said...."That's beautiful"...!
MP173 Excellent photo. Ed
Excellent photo.

Ryan:
I cannot add any more to what the preceding posters have said.
I am using it for a screensaver, on my machine; so I can look at often.
Thanks for sharing it here.

A southbound Union Pacific train crosses the American River on its way to Fresno and other points along the line. This bridge has been in use for more than 100 yeas and has withstood natual and man-made disasters in its time, while continuing to provide its owners a dependable river crossing. Bridging the Gap...
