Letchworth’s ‘Trestle Bridge’ Demolition to Begin Thursday
 
The golden years of the iconic ‘trestle bridge’ that gracefully spans the Genesee River gorge above the upper falls are coming to an end this week with demolition slated to officially begin Thursday, Dec. 17.
. . . .
 
http://www.geneseesun.com/end-line-demolition-letchworths-trestle-bridge-begin-thursday/

Didn't Mark Twain say sometime to the effect that "my death has been prematurely announced?"  That is the case here.  
 
After you get past the panicky head lines and read the article, the second paragraph says Quote:
The bridge is not going anywhere immediately, however, and will continue to operate until a new $70 million bridge is built just 75 feet south of the current bridge by Norfolk Southern, the railroad company that owns the rail. Construction for the new bridge broke ground on Oct. 28 and is expected to carry on through the next 3 years.
Notice, "will continue to operate . . . next 3 years."
 
Yes folks, the existing bridge will stay in service until the replacement is complete.  That is the entire reason the new bridge is being built on an offset alignment.  They have got to keet the railroad in operation during the construction period.
 
(Aren't panic inducing eye catching headlines the way the news vendors propaganda mongers attract attention?

Well, tried to bold part of the quote (last paragraph), but seemingly couldn't. But the answer is "Yes"...

^^I called the author of that article and told him his article was all wrong. He did eventually chnage the headline.
 
I went over on Dec. 15th and took pics of the area that will be closed for the next 3 years.
 
The bridge...

A small underpass under the NS main on Trail 2. This trail is now closed in this area.

^I turned around from that view and took this pic.
 
The new bridge will be straight ahead.

Searching for information on progress on the replacement structure and found this:
http://www.workzonecam.com/projects/americanbridge/portageville/workzonecam
apparently a set camera with time lapse photography beginning with March 16,2016 and carrying through till today (Sept 22)  There is more than one shot in any given day but I had difficulty getting off 6:00am shots, which by this time of year is dark there.  Now that I know about this site I will haunt it fairly regularly.
 
Looks like things are moving along well.  Concrete being placed on the side near the camera, which is on the east end of the bridge, and excavation for abutment appears to be done on the west side.

Not exactly a speedy response, but yes, this was the line west of the bridge when originally built.  It went over the hill and was replaced later by the current line which goes around it.  Would have been nice to have seen this horizontal alignment restored with a better profile which would be economically achievable with mechanized excavating equipment as opposed to the pick and shovel with mule hauled wagons that was what they had when the original was built.  The current west end of bridge curve limits speed to 30 to 35 mph, which was of no significance with the current bridge but will be the determining factor for speed with the replacement structure.

I have been watching the workzone cam and now a message comes up that they want you to register into your account to view. What do you have to do, buy a camera? Was it the construction company that put the cabosh on the viewing? What a shame, cannot view probably because someone is getting something free. I hope I am wrong, but now I cannot watch anymore without registering into "my account". What's the big deal?

I ran into the same thing the last couple of times I tried.  Don't even know how you set up an account.

And here is and article in Railway Track and Structures, dated March 22, 2017 and titled Portageville Bridge Construction Begins.  Actually, it had a few months earlier, but from the picture it appears that they are starting to place the arch steel.  Article appears to be somewhat of a puff piece by the designer, Modjeski and Masters, who are designers of many major structures.

The picture is of surprisingly poor quality.

Another article with a few pictures:
https://www.bridgeweb.com/Arch-erection-begins-for-Portageville-Bridge/4335
The first picture is that in the RT&S article, but much clearer.  To get an understanding of the scale of this structure, look at the last picture in the article.  This appears to be the end section of one of the arches.  There should be four of these sections, one for each end of each arch.  The reason I think it is the end is the large hole at the right end of the beam.  This I think is the end of the arch pin location.
 
Picture of construction is looking east at the east end of the arch.
