"This bridge is an excellent and beautiful example of a pin-connected truss bridge in Michigan. It is noted for its fairly long span length of 139 feet. It also is largely unaltered from its original design and materials. The only thing missing is the builder plaques. The bridge retains a traditional design wooden deck and rests on random rubble type stone abutments. It has been closed to traffic for many years."

After reading about the "random rubble type stone abutments," I better understood why Rick took this photo.

Aban/Penn/GR&I Railroad Bridge

I can't remember another time when Historic Bridges documented a bridge that Bridge Hunter did not document.

Mendon, MI: The Marantette Bridge and Mendon Railroad Bridge

Two abandoned spans sit side by side on the St. Joseph River here. The Marantette Bridge is a 139-foot steel Pratt through-truss built around 1900 by Ohio's Massillon Bridge Company. It's been closed since 1984 and earned a spot on the National Register of Historic Places in 2001.

Just west, an abandoned steel deck plate girder bridge carries the ghost of the Grand Rapids & Indiana Railroad over the river. The GR&I was absorbed by the Pennsylvania Railroad, then Penn Central, then Conrail before the branch was abandoned. No National Register of Historic Places honor for this beauty though.

1930,1990 Guilford Avenue Bridge over I-83 & Northeast Corridor and 1873+1934 Union Tunnel

Union Tunnel is a little east of Guilford Ave. Bridge.

The main span is over Pennsy's Northeast Corridor. It is 174' (41m) long, and the bridge is 321' (98m) long. [ArchivedBridgeHunter]

I learned of this bridge while researching Pennsy's B&P Junction Tower that is a little west of this bridge. I was going to skip another steel arch bridge until I noticed the 1930 date. It looks like a tied-arch bridge, but I have not been able to confirm that. I thought tied-arch bridges were a post WWII development. But this bridge indicates that they were used a few decades earlier.

Amtrak/Pennsy Union Tunnel

I Googled "Hoffman Tunnel" because it runs under Hoffman Street. The results indicated  thatthe correct name is Union Tunnel. I presume that is because the Penn Station was sometimes called Union Station.

I could not get a street view of the tunnel from the bridge because there is a solid wall on the outside of the bridge blocking the view. This view is from I-83.

Street View, Oct 2023

"The Union Tunnel is about 0.6 miles [1 km] long." [maryland]

"The tunnel consists of two parallel bores: the original bore from 1873 has a single track, while a newer bore from 1934 has two tracks." [wikipedia]

Brian Jules posted seven photos with the comment: "Sunbury, Ohio with the repurposed railroad trestle of the Ohio and Erie trail. This railroad  trestle collapsed in 1886 and again in 1910! Finally made right with an iron span in 1910. Trestle spans Big Walnut Creek, location of a Berea sandstone quarry just to the north. Info referenced from The Berea Sandstone Quarries of Ohio, Ralph Pfingsten. Historical photos Big Walnut Creek Historical Society."

1955/56 Sunbury Quad @ 24,000

"The Ohio to Erie Trail is a dedicated multi-use trail crossing Ohio from southwest to northeast, stretching over 326 miles of regional parks, nature preserves, and rural woodland. With the completion of this new Sunbury Trail section, the trail is roughly 85% complete. The trail, named after its endpoints, extends from the Ohio River at Cincinnati to Lake Erie at Cleveland, integrating former rail trails and multi-use trails into a dedicated route​​."

Revenue abandonment
The railroad bridge at Caywood Road, Washington County, Ohio. In 1968 the Pennsylvania Railroad merged with long time rival New York Central forming the Penn Central Railroad Company. The merger went bankrupt and in 1976 Penn Central, along with several other struggling railroads, was purchased by the Consolidated Rail Corporation, in hopes to transform the troubled railroad system into a profitable business. The merger created an ever lasting impact to our area when thousands of miles of track was abandoned, including the Marietta Branch, due to what was considered low revenue. After the last train crossed this bridge on its way to Dover Ohio, in May 1976, just about every mile of the entire line was abandoned.

In the above video, Linda says that this bridge is over the Redbank Creek. But since the bridge is straight, I think she is headed to the eastern portal and the bridge is over Sandy Lick Creek. The bridge on the west side is curved and is over Redbank Creek.

The Pennsy route east of town is now operated by the Buffalo & Pittsburgh Railroad. And the Pittsburg & Shawmut roundhouse is now used by Brookville Equipment Corp. The abandoned railroad west of the tunnel is now the Redbank Valley Trail.

Robert Hartloff posted five images with the comment: "I see a lot of pictures of the famous bridge in Brookville, Pa but never of the Pennsylvania RR tunnel. It appears it was built for 2 tracks. May have been originally Lake Shore and Michigan Southern? My pictures. 10-20-22"

Shane Rosencrance: That's the PRR low grade, nee Allegheny Valley Railroad, the NYC swung across the Coder Viaduct and met the Low Grade at Rose just outside of Brookville. Trackage rights were then shared until reaching the central PA coal fields.
