It was built in 1875 to replace a burned 1852 wooden bridge and then rehabilitated in 1903. The wooden bridge was "the longest and highest wooden bridge in the United States." Plans are to replace the trestle with a steel arch bridge. NS offered to donate it to the State Park since a lot of people trespass on it now. But the state agency turned it down because they said they could not afford to preserve it. So NS plans to spend $1m to tear it down. So preservation costs more than $1m?

Photo taken in Aug 2015. I believe this was the last steam train to cross this trestle in Letchworth State Park NY. Portageville Viaduct. This trestle has since been replaced and torn down. In service 1875-2017.

7/2017 - The two halves of the new Portageville Bridge on the NS Southern Tier Line were joined this week. The new bridge will replace the 1875 trestle and is expected to open next year.

Sean Angelo NS wanted to replace that bridge for a while, as it was getting tired. Plus, there was a 10mph on that bridge, which was a dispatching nightmare. The new bridge should be able to allow speeds of 30mph, helping to keep the trains moving through the southern tier.
AltoonaWorks Sean Angelo The few trains there are, anyway.
Sean Angelo 8 trains a day I've been told.

Construction of the new Portageville Bridge on Norfolk Southern’s Southern Tier rail line in New York reached a milestone over the weekend. Bridge builders installed the last piece of structural steel to connect the arch span. Iron workers attached a pine tree on the steel frame, a tradition that signifies there were no fatalities during this phase of construction.Ken Gentzke Jr The new bridge would allow NS to pull 286,000 lbs max cars over this bridge. Currently they are only able to pull cars around 240,000 lbs max cars. Can't remember the exact amount. These heavier cars went for longer routes.
The $70-million railroad bridge, which spans the Genesee River Gorge in Letchworth State Park near Castile, N.Y., is a public-private partnership among Norfolk Southern, the New York State Department of Transportation, and the New York State Office of Parks, Recreation, and Historic Preservation.
Norfolk Southern hopes to begin running trains on the bridge by the end of this year. The bridge will enable the railroad to better serve customers in Buffalo and the state’s Southern Tier region, supporting businesses, job creation, and economic growth.
Joe Stoltz Actually I think the new bridge will handle 315,000 pounds at a speed of 35 mph vs a substantially lower weight rating and 10 mph speed limit it now has.

NS Southern Tier Line were joined. The new bridge should be in service early in 2018 I believe.
Walt Lankenau I like how they use cables to counterbalance the partial arches before they're connected.
The project has had its share of engineering challenges. For example, NS needed to blast and remove more than 16,200 cubic yards of weathered and fractured rock from the gorge walls. On the gorge's west side, the contractor needed to use large cranes to remove the rock because there was no vehicular access to the gorge floor.
The Class I faced environmental difficulties, too. The bridge is located in a state park that’s home to two federally endangered animal species: Northern long-eared bats and timber rattlesnakes. The park also is home to bald eagles, a federally protected species.
To reduce construction noise that could disturb a pair of nesting bald eagles, NS adopted a plan to drill bridge foundation piles in lieu of the "more typical method of pounding," Swanson said. The Class I also limited the use of explosives to excavate arch foundations.
Although NS develops an annual budget for bridge work, the railroad typically funds major bridge replacements through a separate line-item budget. NS has provided nearly $60 million for the $72 million Portageville Bridge replacement, while state and local funds will cover the remainder. The project marks the largest public-private development that NS has ever developed for an individual bridge project, Swanson said.

At 2:20 p.m. Monday, Norfolk Southern general merchandise train 36T became the first to cross the new Portageville Bridge.

At 1:40 a.m. on December 11, 2017, the last train crossed the old Erie-built 1875 Portageville Bridge over the Genesee River Gorge in Portageville, New York. At 6:00 a.m., the track would be taken out of service for 8 hours to be cut over to the newly-built bridge. For more information about Norfolk Southern, visit www.nscorp.com.
[Note that they used the new bridge to hold the lights needed to take a night photo of the last train. It really captured the truss+girder design of the trestle.]

[American Bridges has several more photos and a detailed explanation of how this tieback system held the arch halves until they were connected. Erie started with an 800' timber trestle in 1852. But when that burned in May 1875, they replaced it with an iron bridge in three months. In 1903 the spans were replaced with steel girders and pin-connected trusses. But the iron towers served into the 21st Century.]

David Andrew Wieting Looks like the stone piers remain in the river. The removal of the old bridge really does open up the views of the canyon. New bridge is worthy of inclusion with the famous two track version in NM on the BNSF over the Rio Grande.

John Kucko Digital posted five photos of the inspection truck in operation with the comment:
Trestle Tales: One of the most dangerous jobs around was that of bridge inspection of the 1875 High Bridge at Letchworth SP. This soon to be gone trestle had to be inspected very regularly, meaning folks would be hanging 230-240 feet above the raging waters of the Genesee River and the Upper Falls there. This was always an amazing sight to see as inspectors examined the bridge from stem to stern. I remember one telling me "you just hope the truck arm is working well that day." The new arch has a much safer means of inspection--a secure catwalk that allows for inspection and regular maintenance. "Old Shaky" (what the trestle was referred to by train engineers and conductors) is in its last weeks--built in 3 months, lasting 142 and a half years.
John Kucko Digital posted a photo the "Genesee Arch Bridge" in a dedication ceremony on May 24, 2018. Norfolk Southern's ceremony included stopping a westbound on the bridge for a few minutes.
|RailwayAge's article on the dedication|
The first Norfolk Southern movement across the new bridge occurred in December 2017, following two years of construction. The span it replaced, the Portageville Bridge, can be seen at right. It has since been dismantled, with portions preserved for historical purposes.
