"At one point alleged to have been built 1812 by James Moore II, father of the founder of nearby Bucknell University, which at the time would have made it the nation's oldest covered bridge, and it was promoted as such on postcards and tourist brochures. Later research in the 1980s proved it to have been built in 1830 instead." [ArchivedBridgeHunter]

Linda says a bridge was built here in 1812, but it was reconstructed in 1830 after it was damaged by a flood in 1828. Note the 1972 flood water line near the top on the left. That was from Hurricane Agnes. Restoration work was done in 1981 using wood from an 1830 school.

Lincoln Highway Overview

Brian Butko posted
If you're following the Lincoln Highway through Nebraska, be sure to get off US 30 between Duncan and SIlver Creek to travel a stretch of gravel LH that includes this iron truss bridge across Prairie Creek.

David Sellman commented on Brian's post
My wife and I drove over this bridge on June 7 of last year [2025].

"Section of Lincoln Highway in southwestern Platte County, Nebraska; looking northeastward across the Prairie Creek bridge. This is part of a 1.2-mile (2.0 km) section of the highway that is listed in the National Register of Historic Places under the name Lincoln Highway-Gardiner Station. The sloping-topped brick structure at left is a Nebraska state historical marker."

In 2019, UP replaced the railroad bridge that is in the background of Brian's photo at the top of these notes. We can see the top of the truss in the right side of this view.

The replacement bridge. It looks like modern steel girders can be more shallow. Or did they use more piers?

Steam-Driven Lift Bridge over Oswego Canal

(Satellite?, I don't even know which town this was in.)

Cori Willson posted two photos with the comment: "The West Shore Railroad crossed the Oswego Canal on this steam-operated vertical-lift bridge. The engine and its attendants occupied the small control house on top, which rode upward each time the cables rolled over the four large sheaves to raise the bridge span. This photograph was taken in the early 1880s. Within a few years, the coal sheds and stationary crane visible here (used for unloading canal boats) were replaced by modern coal pockets and a traveling steam elevator for distributing coal from the Delaware & Hudson Canal Company (see second photograph)."

Lincoln Sander IV: The West Shore was completed in 1885.

As Lincoln's comment suggests, Cori probably has the wrong railroad. The only railroads I could find near the Oswego Canal were New York Central & Hudson River, New York Ontario & Western and Delaware Lackawanna & Western. 

1900/00 Fulton and Oswego Quads @ 62,500

And the only place I could find any railroad crossing the the canal was in Oswego, NY.

This bridge is on the correct angle, but it is way too high to be the bridge in the photos.

Mark Barnett posted six photos with the comment: "I found these photo's I took back in 1992 to 95,of the Illinois Terminal bridge over the Sangamon River just south of Sherman between Sandhill Road north of Springfield.  First one is looking north towards Sherman, then I went over on the old P&N bridge and took a couple more looking east then worked my way north back to the IT looking south. This bridge has been gone for several years now."

Mark Barnett posted 10 photos with the comment: "May of 1998 we called it a rain day and Mike Fortney and I made a road trip back to the Illinois Terminal bridge over the Sangamon River when we got word it was to be removed soon. I took these final photo's all looking south except for the final one looking north towards Sherman where we parked at the rest stop on 55. Also notice one shot of the P&N bridge to the west of the IT. The water was high that day and mother nature was trying to take over the bridge on the north end."

The bridge was extant in Apr 1995.

But it was gone three years later. And by the next image, 3/2005, the other bridge was also gone.

Flat Rock Dam, a graffiti covered canal lock, and fresh pavement that'll probably be a continuation of Flat Rock Road when whatever new developments are complete

This has more graffiti than a boxcar.

A lot more.

Anderson Tunnel near Whittier, AK, longest highway tunnel in North America

(Satellite) 

This tunnel is the only land access to Whittier, AK.

It is a railroad tunnel that allows one lane of traffic when a train is not scheduled. The vehicle traffic alternates direction every half hour. The fans have to be reversed when the traffic flow is reversed.

The tunnel is 4km (2.5 miles) long. [tommorow.city]

Street View, Oct 2021

Because the tunnel changes direction every half hour, it has parking at the entrance to queue up the cars waiting to go the other direction. The tunnel closes at 11pm so if you are not careful, you can get stuck in Whitter overnight.

There used to be railcar ferries, but they don't look like they are active anymore.
